That thing is huge! I have always been really interested in those structures! It was incredibly difficult for me to make a little tower out of toothpicks and glue in school one day, I can't imagine building a tower like this! I can't remember who said the quote, but it goes "anyone can build a bridge, but it takes an engineer to build a bridge that barely stands." It seems like that quote applies here because those things are definitely not over built! Is this a radio communication tower?http://www.danmax.com/
