Gordo1473,
I went through this same scenerio with my son many yrs ago. It is a game of chance with kids that age, they say they are interested and really want to shoot/learn, until they actually have the bow in hand and realize it takes time, practice, etc. There can be some rather large expense involved with a good set up.
Here is what I did, I stopped into our local archery shop/range, (privately owned) and explained my situation, the owner was well aware of the scenerio, he'd heard it 100 times before. So, he gets a youth bow, set it up for my son and took him to the upstairs range and let him shoot for 15-20 mins. Then offered me a 4 practice sessions (30mins ea.) for $20.00 for my son to see if he was going to "continue" to enjoy the experience. He stated most kids will stay or quite within 4 sessions.
I my case, my son picked up on it very quickly and is now into his 3rd yr. of shooting.
It is only a suggestion and I don't know how cooperative your local shop may be.

PS: there is a really good deal on a youth bow in the classified.
