I'm learning to read between the lines. When I first saw this post figured it had to be the old two coffee cans and a piece of string stretched between the two. Growing up in south La. that was what we used as a walkie-talkie. We was kind of poor and that's all we had.
I'll have to throw that Vodaphone mast thing at some of my buddies and see if they've ever heard of one. More than likely, they'll think of the two coffee cans and a string.
