I guess ill continue looking to find our place. ( im looking for a chabad comunity with a chabad school , fresh air with back yards and all in all a good quality of living ( open to outside of the US)) suggestions ?
If you want a Chabad school why did you even consider DEN?
For a Chabad school you have a few picks: NYC, ORD, LAX, MIA, DTW, and the yotzei doifen of them all PIT. There ain't that many options. Unless you want to start including a Chabad run community day school that is really for mekurovim and not for your kids.
Of the cities I mentioned above, the only one that has "fresh air with back yards and all in all a good quality of living" is PIT. And it's the most affordable (on par with DTW.)
