Days 3-4
Friday morning, we called Moishe's car service for 11AM, headed to Staten Island to my brother-in-law for Shabbos. The car came a few minutes early and the driver made no move to rush us. The cost was $110. We had originally packed a suitcase specifically for the Staten Island trip, so getting out was relatively smooth.
Eltingville is home to a Young Israel, a branch of Oorah, and a community kollel and yeshiva (the latter of which was closed for bein hazmanim). The family we visited had spent many years with us in EY before moving to the koller, and we thoroughly enjoyed the time we spent with them. (We helped occupy their kids so they could prep for Pesach.

) The neighborhood was peaceful and quiet, and within walking distance of an Aldi, Walgreens and CVS, as well as the MTA's Eltingville transit center with a local bus to Brooklyn and express buses to Manhattan.
Day 5
Sunday morning, we went on a day trip to Brooklyn, taking the Staten Island shuttle. The shuttle costs $10 per person (except little kids) and you can pay with a card. We needed to be driven to the first stop, though. In Brooklyn (they drop off along Ft. Hamilton and 49th street, just like many other frum bus companies), we got around with quite a bit of walking and one bus ride, visiting one brother-in-law, a cousin we are close with, a very good friend of mine and his family, one choshuveh Rebbitzen that my wife is close with, and my Rebbe. We had lunch at Kosher Hut because that's where we were at Mincha time.

This friend and I have a "minhag" of going out together for ice cream (this holy custom is more than fifteen years old), so we went to the Ice Cream House and got some. At our last visit at around 6PM - another friend of the family - the kids fell asleep on the couch. As such, we took another one of Moishe's car service rides back to Staten Island ($90). Total number of lollipops my kids got from the people we visited: four.
Day 6
I left my family in Staten Island and caught a ride with an avreich to Brooklyn. I had a few errands to run (after taking a short walk around Bingo like a good tourist).
I headed into a branch of TD to determine the status of our accounts there. Originally, I had been very happy with them, but a few years back, they started shutting the accounts on the slightest strange activity - and after hours on the phone, telling me I could resolve the account "by walking into the branch." After this happened a few times, we stopped using the account, and a few years after that, they sent us a letter saying it was closed. I don't trust anyone, so I wanted confirmation. Instead, I got a few printouts of my cousin's accounts being closed! (He has the same name.) Unfortunately, I only discovered that she had been looking at the wrong accounts after I got back to Staten Island, and I never got actual confirmation. Maybe next time.
In Chase, I cashed a savings bond my parents had dug up. It had been issued shortly after I was born for $100, and even though it had long-since matured, it continued to accumulate value. It took the teller and bank manager together about twenty minutes to figure out how to process it, and then they deposited $415 into the account. (I think the $100 from back then was worth more than that, but hey, it was a cool gift. I think it made the teller's day, anyway.)
I decided not to be cheap about being contactable in the US and rented a phone at Hoffys - $25 a week (iirc). The phone had texting but I pretended it didn't so I would be potur from getting and responding to them. I stopped into Amnons for lunch and into China Glatt to get some food for supper at my parents, as I couldn't predict the availability of food there later. I also picked up some replacement food for my brother-in-law's house, as my kids had made a significant dent in his supplies.
The avreich headed back into Staten Island in the mid-afternoon, and after cleaning up where we stayed, we took the car service back up to Pomona. The driver asked if he could charge us $6 more to take a faster route, and I was happy to say yes at those prices. The kids were asleep by the time we arrived, so we were able to grab a Maariv at Rabbi Scheiner's and eat before going to sleep.
