I was just getting ready to ask about this!

I found 1000 feet of 6 inch for $2000, and 5000 feet of 4" for $5500 
(all of it is used, but looks good).

How do you couple the sections together? With the regular clamps 
they use? How often do you need to guy it?

I'd like to make some 80-100 foot verticals from it if I could. I was 
thinking of getting a sign truck to pick it up and hold it while the 
guys were pulled tight.

This seems like a cheap way to get some verticals, if it will stay up.
