For the last 3 years running Lake Tahoe's Slow Rollers bicycling club has put on a costumed bike parade, which last year I filmed as a contender for the Gueiness world record for "World's Longest Bicycle Parade" but this year the spring weather was rainy with a threat of lightning and the turnout wasn't as big as usual.
It's usually from the Y to Stateline; this time it was from South Shore Bikes to Mo's Place, so I missed the actual parade; but I caught up with the slow rollers at their afterparty and got this video with all the riders in their costumes.
