Thanks for the feedback OregonMouse! We actually tie into real time availability, so the sites you see are actually available. That's one of the most unique features of the site in my opinion.

I'll definitely be checking with Packlite to comply with the rules. Right now we're just in beta, so just looking for feedback from you guys. We want to build a product that you will use...hence why I am really pushing for backpacking in the near future.

Thank you! Would love more feedback..
