I had a long talk with the owner of
Alaska Grizzly Safaris at a photo show last week. I know some here are interested in something like this, so here's the relevant info:
His lodge is between the McNeil River and Brooks Falls, so the best of both worlds. He has good access to the tidal flats as well if you want to watch the bears clamming. Additionally, he claims to have 'secret spots' where you could walk right up to the feeding bears. Trips start at $5k p/p, all-in, including daily bush flights as needed.
Most importantly, he is willing and able to accommodate Shabbos schedules, and will provide or accommodate whatever you need as far as kosher.
Reach him through his website or at JacquesAK@aol.com.
