Rabid 29er fan, that's me.  My buddies make fun of me and my bikes
frequently.  I like to think that they're just envious.  Oh sure,
they'll ask if I stop at all RR crossings or they'll sometimes make
beeping noises akin to what you'd hear when a school bus is backing up,
but hey, it's the envy talking!  I started out on a Fisher Mt. Tam 29er,
affectionately referred to as "Large Marge", and am now racing primarily
on a Fisher Supercal 29er (referred to as the O.R.B., short for "Off
Road Bus").  For the record, don't ever use "it's amazing what you can
do on a big bike" as a pick-up line in a bar; 29ers may rule the trails
but they won't necessarily bring the ladies running.
