This happened to me yesterday at my workplace.
I was performing the mundane task of hauling some packing boxes out to throw in the trash dumpster. On my way, I noticed some black objects lying behind the dumpster enclosure alongside a stack of discarded wood pallets.
A closer look revealed them to be a pair of used, heavy duty audio monitor stands!
Someone from one of the neighboring businesses had apparently tossed them out there, likely with the intention of someone - like me - finding them and making good use of them.
Of course, being a rocket geek, I immediately recognized them as a splendid pair of wide-footprint MPR-worthy launch pad tripods!
I couldn't believe my luck in stumbling across these items.
And I didn't even have to actually dig them out of the dumpster!
Everything seems to be in working order with them, and they only need a little cleaning and paint touch up here and there.
Here's a pic of one of the units set up in my basement shop, all ready to be converted into a launch pad.
At the moment, I am not into MPR, but perhaps this beastie could be the catalyst that would change all that.
We shall see.
