Update on the FREERailing:
It is portable. It was a bit unintentional, but now 2-3 traceurs can carry this whole thing around quite easily. (two carry the two different sides, and one carries rails.) I'm pretty glad you said 3' - 3' 6", because that was the conceptualizing measurements

Estimated cost is under $40, (waaay more expensive than I want) as long as you can find cheap steel piping and couplers.
So, I just checked over the schematic w/ my dad, he suggested a couple cool things. I'll show you guys the schematic in a couple minutes. He pointed out a 2x4 is actually 1 1/2 X 3 1/2 in. Damn... minor inconvenience, no biggie. (
Real Lumber Dimensions)
This pipe will be ideal. 1 1/4 by 60 inches. (Don't buy that one, look for those dimensions though. Once you find the price of that, multiply it by two and add about 5-10 bucks. There is the estimated price.)
WILL POST THE SCHEMATIC IN A FEW MIN.
So, railing dimensions: 3'6" (height) X 5' (length) X about (15sq ft) footpint.
