If you’d like to bike to work and back, but worry about getting home quick in a family crisis, check out the Emergency Ride Home program at South Florida Commuter Services.
Commuter Services is the project that aids and promotes car-pooling and other alternatives to the personal car for transportation in Broward, Miami-Dade and Palm Beach Counties. They're at 800-234-RIDE (that's 800-234-7433). You need to be registered in advance -- but once you're in you get up to six free taxi rides home in a year. Tell 'em you heard about them here, won’t you?
