Mini-quads are to ATVs what minibikes are to dirtbikes. They are overpowered, underweight, top heavy, and just flat out scary. They are fine if properly supervised, but the can't do what a full sized ATV can in terms of climbing or handling, and if the parent or expedition head isn't watching, helmet or not, there is going to be sorrow.

They'd be fine if the lowered the power and upped the weight at or below the axels, but until they do, I shudder every time I see one. I'd much rather see a kid on a minibike- those won't roll over you, just tip over, if you dump them on a hill, and they don't have the power.

As for teaching someone to shoot, if you are doing it to convice them not to shoot, you're doing it wrong, and for wrong reasons. As for teaching early, I would say you can't be too early with the safety lesson (stop, don't touch, get an adult), but you can weight to teach them to shoot. Me, I can't imagine choosing to ride a bike than be on the range, that's just abnormal to me, but to each thier own.
