I've seen mention of Buffalo Creek there, but have never been to the range - I'm on the east coast. They apparently have a 600yd range and an active HighPower program. I think that they've been running these clinics for several years now.
$45 is reasonable, especially w/ a gun rental and ammo. It's probably a wash for the club, just a way to ensure they they're not losing money on the program.
