Most of the clubs I have looked into will let you visit and take some initial training lessons without joining. The last club I belonged to would let you fly 5 times but you had to be on a bubby box with an AMA certified instructor, and you had to have your AMA membership. I went to several of their meetings and eventually joined. Their dues were $75/yr, but they did not prorate. I joined in the middle of the year but had to pay full price. I assumed (should never do that) my next years dues would be 1/2 (that's how the AMA does it). But alas, I was told I had to pay for a full year again. I decided not to rejoin.
So, like Allan from down under said, go and introduce yourself, and ask a lot of questions.
