What happens when the wind blows from behind the target (or do the hinge
legs extend forward as well)?

In any case, I like it. I stopped using the last one I made, which used
T-posts and routed 2x2s extending up. I got tired of carrying that and the
sledgehammer, but mainly I didn't want to be shooting at T-posts.
