Same ideas that I use
I have a one week problem each year using my vacation home without my normal ISP. So I try to find a friendly neighbor and suck off them (didn't work because they couldn't remember their router password).
I then attach my antenna to an extendable pole (tree trimmer) and move it arround my yard searching for my more distant neighbors without security to their wireless. Kind of catch as catch can. Disadvantage is the length of USB runs to my desktops inside my house, but it gets me by with PPRune access
