Last year was my first year bow hunting and when these guys tell you that you will get hooked... they are not kidding!!! It is amazing and you are going to have a blast!
If you have a Dicks Sporting Goods down around you, I would go there. That is what I did and they have a lot of good starting bows there at good prices. I got a Martin there and it turned out to be a very fast bow and they set everything up for me.
My biggest tip would be to PRACTICE!!!!!! I picked up my first bow ever 3 weeks before opening day lol... granted I spent at least a half hour everyday before season flinging arrows to get ready. The first deer I shot at I missed him low... But I am glad I did because the next weekend a huge 9 pointer walked 20 yards infront of me and in Indiana you can only get 1 buck a year... So count your misses as blessings too lol
Good luck this season!!
