Demo clubs/balls are both EXCELLENT ideas! Wow! After reading all these ideas, I've gained a new understanding of why there isn't a practice range yet! It's no small thing to put something together like that, and would probably be one helluva challenge for any programmer... someone better get started on it right away! heh-heh! J/K. ;)
Another idea that I don't necessarily desire, but thought I'd mention: at a local range, there's a lake to hit over... talk about "yip management"! :O
