Benjammin,
There must be some cable show you could star in.
Perhaps for an entire season.
I'm feeling a tremendous kinship.
This forum could start a co-op.
REI started as a co-op and technically still is.
I have no desire to bother with a garage sale but if there were a consignment shop for outdoor gear I might go for that.
Have an extra mountain bike (actually I have three mountain bikes, one I consider a spare), a few hardly-used campstoves, couple more tents to sell. And then there's the unused organizer bag collection....
Am perpetually one great bag away from being organized.
