i went to the KHSC rifle range wednesday (6/29/16), got there about 10:30, leisurely set-up and relax. by 11:30 they had a wait-list, every shooting position was occupied, and the range hadn't even "opened" yet. when the range went hot at 12:00, was packed to the gills.
went back on thursday 6/30/16, got there about 10:15. there was nobody there, i thought i had misread the schedule and maybe it was closed. no, just empty. was talking to one of the range officers, he said that on wednesday, the wait-list didn't clear until 2:30. when the range went hot at 12:00 on thursday, there was probably about 20 target frames down-range. it did pick up a little by the time i left at 1:30. but still, not to the point of a wait-list.
range officers said that this past wednesday high-volume was very unusual. i'm glad i had gotten there early.
