Hello Piikki. Welcome. My kids just did their OW at Hearthstone this June (photo attached), and we returned there again Sat. to check out some gear we picked up from the dive shop Lorien speaks of (and also to go back out to see the airplane. My daughter had not gotten out to see the plane on her earlier dives). The shop in Glens Falls is Rich Morin's and I am impressed by the professionalism they showed. I drove two hours each way for my kid's classes with Mr. Morin, and I am quite satisfied. Lorien has also mentioned a local (Albany region) dive club: something like Albany Aquanauts? that you might want to check out for diving partners, trips and contacts.
