:60: I recommend that you enter 420 into Wikipedia.com and you'll get the history & culture surrounding this number...I had the same question....you can get a lot of different answers depending on who you ask. But the # does register w/ almost every user I've ever talked to. ALWAYS MAKES MY MOUTH WATER WHEN I HEAR 420!Hey all!! I'm new here too...and new to the 420 world!! Since we're all about good times here, I must ask a question that is sure to get at least a chuckle out of ALL of you: just what the hell is the significance of "420" in all this anyways?? There...now you can laugh, but someone PLEASE set me straight on this!! thx much!
