At an event you either like attending or one that you are in some way responsible for organizing, suggest to those organizing the event, those working with you, and/or assign a member of the organizing committee to connect with local bike shops and organizations to have a bike valet. Bike valets are the brain child of some brilliant cyclist somewhere and we have no idea who to give credit to, but the idea and implementation is just genius. Event goers are not only willing to attend that special occasion because they won't fear getting their bike stolen, but more people will get on their bikes to attend because it is fun, good for the environment, good for their health, and best of all, they don't have to sit in traffic, pay for parking, pay for gas, or inhale all of the disgusting fumes from auto exhausts.
Just to review, the benefits of bike valet: (not in any particular order)
1.More people attend your event
2.Improve general health of population in your community
3.Bikes don't get stolen
4.Improve general health of local environment
5.Less gas consumed, needed, wasted, and produced (errr, maybe not produced?)
6.More people will have fun because they arrived less cranky and healthier
7.No more looking for parking
8.No more paying for parking
9.No more paying for gas to sit in traffic and look for parking
10.All the money saved translates into more enjoyment at event because the pinch is off the pocket
11.Less fumes
12.Less cars on road
13.One less car = one less car accident
14.Event organizers hold event again next week, month or year because this event was such a smashing success.
