I've been out there 6-8 times in the years it's been open. You definitely need to check their website for current operating hours.
http://www.range-1.com/ The website also does a fair job of representing the range and its programs. The range and affiliated facilities have pros & cons depending on what you're looking for. If you are "vetted" (by the range staff) it's possible to do some decent training. In contrast, McKellar's is very restrictive for anything more than plinking/zeroing. FWIW - I'm debating a membership there myself (probably later in the spring). Peregrino
