If you're not a regular viewer of *RTM* or a fan of the sport, slacklining probably looks pretty crazy. In Latvia, for example, they're not used to seeing what slackliners can do. So when a bunch of people spotted a man slacklining between two skyscrapers, they were blown away! Since we're experts, we can tell that the man had a safety line, but not the people below, so they probably thought it looked much more dangerous than it actually was.
