I needed a marsh seat for the coming duck season. There were some old crutches in the garage that I thought I could repurpose. I'm sure some of you are in the same situation, so I thought I'd share.
It still needs testing in the marsh, but I suspect it will work well.
I've often looked at crutches in thrift stores and thought, gee, those look like they could be repurposed for something. Strong and adjustable. Nice work!
