I used to work at a VA (in a non-medical position) and I can say that we had a TON of volunteers rolling around. I loved the atmosphere of the hospital, not because it was an awesome place physically (think 1960s bomb-proof) but because everyone was so committed to the same kind of core values of serving veterans. Also, hands down it had the NICEST people (in all departments, from chiefs of department on down to janitors) working there, I'm sure because the ppl that work there actually want to be there. I would say go for it, for sure.
