I've been to 4 ranges so far and my experiences have all been good though I must admit, I'm waiting/expecting an experience like mauser06's...cause there are jerks everywhere; nothing I can do about that. I have met a couple of very nice/knowledgeable guys though.
Right now I'm very fortunate. I have access to a 300yd range that's been vacant almost every time I've been there and it only costs me $15/year!
