I do not belong to the Hindu faith but I am very curious and would like to learn more. Are there any times or opportunities for someone like me to stop by and ask some respectful questions? I would greatly appreciate it.

There is a bunch of books you can read as much as you can, All the answers you can find. Hope this helps

ISKCON Boston has public programs on Sunday and Wednesday evenings in which a lecture is given. Listeners are welcome and encouraged to ask questions. You will get 1:1 opportunities on these days as well.

Yes, you can. There are gathering every Sunday afternoon between 4:30 pm and 6 pm where you can ask any questions you might have. I can also try to answer your question if you want to ask. I go to ISKCON of Ct in East Hartford/Glastonbury. You can reply to this thread I guess or contact ISKCON of Ct phone number.

I think they will surely entertain you and try their best to answer your questions but before dropping by you should call them and make sure about their duration. You'll get their number on website
