Lil'Bravo and I shoot there from time to time... We have been lucky for the MOST part, and been there when the range was mostly or totally empty!
However, the last time we went there, all the firing lines were full, we got out to do a visual and see how long a wait it might be... In 3 minutes being out of the Jeep, we counted no less than 12 unsafe acts with perceived to be loaded weapons. We looked at each other, made a mad dash for the Jeep and got the HELL out of there, before we ended up a statistic!
Going to Potts range is like putting your life in someone else's hands!!
Ill just stick with my buddy's private range.
