i had lived in seattle for several years before i finally ventured on the underground tour. since then i have taken the tour several more times with visiting friends and relatives. admittedly, it does get old after the second time - the jokes are written into the script, so you hear the same puns over and over. however, the first time it is very informative and mildly amusing. it's cool to walk underneath the square - double entendre intended. it's a good alternative for some hot seattle afternoon when you're about to go see some crap movie just to sit in the air conditioning (yeah, i know those times are few and far between but i already said don't go more than twice ;)!
Pros: informative, interesting, unusual
Cons: musty, stale jokes
