Spare the Air Day on June 19, 2008. Just in case you have not already heard, a quick reminder that this Thursday, June 19 is a Spare the Air Day, and the only planned day of free transit service. It is also APTA’s 3rd Annual Dump the Pump Day. So be sure to take advantage of the free transit, and then continue to use it after Thursday, even when it is not free! BART, Caltrain, AirBART, ACE, and Amtrak/Capital Corridor will be free until 12 noon. Alameda-Oakland, Alameda-Harbor Bay, Vallejo, and Golden Gate ferry services will also be free only until 12 noon. Bus and light rail service around the Bay will be free for the whole day.
True that this is that last free day this year? http://livinintheloin.com/2008/06/14/free-transit-day-going-green-or-going-going-gone/
That seems to be what they’ve said.
