OK guys take it easy on me here... My son and I are going to start bow hunting this year. I bought him a Bear Cub last year and a 3d target and let him shoot, I learned how to shoot a bow when I was younger but its been a long time.
This year I'm upgrading my son's bow to another Bear Cub, this one is a 35-55# pull, I'm not sure about the rest of the stats as Its being given to him from a family member. My son turns 10 this weekend. I also recently bought myself a bow, Last year I shot my grandfathers old Ben Pearson but I've decided to put that bow up as I belive it has a pretty good antique value. The bow I bought for myself is a Hoyt Raider, I belive its an early to mid 90's model. I want to make sure this is something he and I both are going to stick with before I go sinking alot of money into it. We already sink enough money to keep the wife mad into fishing.I've attached a picture of the bow I bought. Now I'd like lots of tips and pointers from you guys. Economical upgrades or additions I should make to mine and his bow, tips on shooting from the ground, we do not own a deer stand and before I can teach him to climb a tree with one I need to learn myself. I've heard alot of horror stories of guys falling out of trees so I'm a little spooked by that. So for now we are going to be shooting from the ground. Any tips you can give me about shooting from the ground will be greatly appreciated. Any info that I probably don't know about the bow I purchased will be greatly appreciated. Anything that we 'have to have' (trust me I know what that means.. I fish) or basically just ANY info you can give us will be VERY appreciated.

Thanks
J
