I hate to rain on your parade, but I wouldn't bet on being able to shoot on the upper range (where the 600-1000yd section is) this weekend - Washington state long-range championship will be going on Friday thru Sunday, 0900-1600 or so. Before and after the matches, traveling shooters may be camping on the range.
Of course, you're more than welcome to come shoot some F-Class any of the days... just bring at least 51rds of ammo to complete the individual course of fire on any given day. There will be long-range practice on Thursday and Monday. If everything works out, I should be there Thursday thru Sunday - not sure I have enough bullets to shoot Monday too! (Theres another LR Regional the next weekend in Portland I have to go to as well).
See ya there. Unfortunately I'll be trekking back to Wenatchee each day to take care of stuff at home (online college classes, keeping the wife from getting too pissy about me being off 'playing', that sort of thing) so if you see me, I'll probably be busy with the match!
