There was a "free" table at the rally. At some point someone left what looked like a pile of folded up black reusable shopping bags. My wife needed one so she went over and unfolded one. Then she kept unfolding and it turned out to be a large bag which we instantly recognized as being large enough to hold a zero gravity chair. There were two of them. The label said "TravelChair". We looked it up and it turns out that it's made specifically for a zero gravity chair of which we have two.
I made my rear box to hold specific items that I wanted quick and easy access to, including two zero gravity chairs. We were using misc. ill fitting bags but these bags designed specifically for those chairs are so much better.
So, huge thanks to the person that put them out on the "free" table. They've found an appreciative home.
