I'm thinking ahead to chol hamoed Sukkot and hoping to build a portable sukkah. I'm thinking 4' square and 5' tall; I have a bamboo mat for the schach (roof) but I'm trying to brainstorm what to do for a frame. I want something light enough to carry from my office to the park down the street, and easy to set up and tear down in a minute or two. And I see no reason to spend more than $50.
( Brainstorming begins behind the cut, and continues in the comments. )
