first time using it this month. part A says it expires on the 15th. does that mean i still use part A as a flash pass tomorrow or do i need part B? the bart plus brochure- not very helpful!
also i must say this is one good thing about bart. if you buy the high value versions, you end up saving $3 on a monthly muni pass, plus you get 2 last ride bonuses. not great, but not bad either.
