Welcome to Trad Gang...
I went "Traditional" 2 months ago.
I, too, thought 45# would be a good start but when I started shooting bows at that "draw weight" I quickly found out 45# was way too much!! So, I bought a used 35# recurve. Practiced with it everyday and just recently bought a Bear 45# Grizzly and I could not be happier.
As for going to the archery range empty handed, Just go, I'm sure somebody will start working with you. Start researching and dont be afraid to ask questions.
