How about creative vehicle attachments?

I once used 3/4" EMT, couplings, and T condulets to construct a frame for a float in a local parade. Basically, a box frame built around a minivan to hold cloth coverings with signs/banners on it. Hung off the luggage rack with kindorf and conduit hangers! I have a picture of it filed away somewhere (pre-digital) will have to dig it out...

Once used 1/2 inch EMT as tentpoles for rigging up a tarp off the back of the same van at a tailgate party (Grateful Dead tour in pouring rain! [Linked Image]). Attached the tarp to the EMT by dropping bent scraps of allthread through the grommets into the open end of the pipe. The site of us barbequing and partying in the pouring rain attracted quite a crowd looking for a dry place!

Still miss ya, Jerry!
