(You might need 8 quarters per ride by luly 1 if the transit agency running Muni has its way (but the Bd. of Supervisors can override that decision).)

Seriously, though, there's another way to avoid traveling with rolls of quarters. MUNI still sells coupon books (paper tokens) for $15 per book of 10-ride coupons. It's perfect for those not using MUNI often enough for a weekly or monthly Pass and yet who don't want to travel with loads of coins. See this site http://www.sfmta.com/cms/asystem/far...=Token+Coupons, as to where to buy these coupon books.
