Hello - I am 42 and considering a visit to the Vet Tech Institute on 7th Street, 15222. If I enroll here I'd move from a NY suburb and want to rent close to school and within walking distance of grocery stores, bank, etc. as I do not like to drive. I heard it's a very walkable, liveable city, but how safe? Will I find a mix of people in my age range here? Thanks for any guidance, I'd like to visit in the next week or so.
