You know what I will add my two cents anyway.
The class is great, bring all of the stuff they tell you to. I personally shot around 250 rounds but could have launched 300 if I had them. You will learn a ton, I live in Denver and base on what I see for weather I would plan on wearing the coolest long leg/sleeve stuff you have, and bring a hat or something to protect your neck. It will be sunny and hot, plan for it.
The first morning is a quick powerpoint then right to the line for a fundamental eval. After that back in the class for a few hours, they will break for lunch at this point. This is the only day I would head back in to town for lunch, on Saturday and Sunday I recommend packing a lunch and staying at the range Frank and Mike brought out some of their stuff and I was playing around with my .22 trainer, lots of fun conversation to be had during that time and it was fun to shoot Mike's Voodoo, Frank's 224v, etc..
Bring lots of water, bring sunscreen, a small blanket or crumpled jacket may be a nice chest support after 2.5days on your belly. It is dusty, plan on a dirty gun, draping it with a towel when not shooting may be a good call to help.
Other than that you will have a blast, prior to the class I had not shot past 600yds. By the end of class I was making consistent hits at 1425 in 17mph winds. It is well worth it, I really hope they add a level 2 class next year!
Best,
Blake.
