Free Unistruts (Score 1)

I've created a rack, desk and shelving by visiting my local street maintenance depot and talking them out of some of the "Unistrut"(?) posts that they use for street signs after they have been run over by some driver. The un-bent portions are 4 to 6 feet long and the maintenance guys seem to be glad to be rid of them. The posts are square tubing about 1 1/2", predrilled on all sides.
