Hey Tripp, just saw your message - a month and half late. Yeah, it was my retired fire marshal friend (and fishing guide) who brought me up to speed on the issue. I was pretty incensed at the DOT for what I thought was an over reaction that really left Lite Cylinder with no choice but to fold up shop and go out of business.
I really like my lite cylinder. We used two on our June/July Grand Canyon trip - just kept them buried in the gear pile and out of the sight of Ranger Peggy, just in case...
