For starters, wipe the grin off of your face. It is going to be a lot of fun. There is an absolute wealth of information on this site, and on the Bowsite and Stickbow. Take your time and read your way back through all the adventures that guys that have already gone have shared. You will not be sorry. Not only will it get you excited even more, it will answer some of your basic questions and then you jump off from there. The only thing that I have to mention is that you are shooting on the light side. You will certainly see a number of posts about game taken 45-50#, but I would look at 50# as a minimal goal (IMO): you have plenty of time to work up to that if you decided to. So, read on and enjoy it.
