I'm also in MD. My son was right over the 30lb minimum when he first started bowhunting. It's pretty impressive how quickly the strngth of the young-un's increases. Even with just a pound or two a week, he'd be ready by the start of the season. But I see you would need a bow that allows for a seperate draw weight adjustment.

I would keep the shot distance limited to 20 and under and , even then, only when everything is perfect -- i.e.--shot angle, etc.
