Fri Oct 31 2025 critical mass Halloween bicycle ride San Francisco meet 5:30 PM 
Justin Herman Plaza SF 
Market at Embarcadero SF 

then when you hear the bike bells ding ding ding at 6 PM you know it's time to put down your joint and your beer and hop on your bike 
6pm bikes usually ride SW market Street SW Geary NORTH to Union Square for three clockwise circles for all the stragglers and slower to catch up but then they either shoot off towards Castro or Ocean beach or mission or up Polk towards fisherman's wharf or the old Exploratorium at Palace of Fine arts to bicycle underneath the columns it's fun and Halloween is the biggest ride of the year used to be 1000 bikes in costume might be less now other days are fun too but Halloween is the best because with 1000 bikes you can blow through all the red lights as other bicyclists and or motorcycle cops will block off the side traffic to give you free passage then

Broadway tunnel Geary tunnel Stockton tunnel SF is so fun to fly through on a bike when you don't have to stop at red lights it's truly a small well designed city 
Thin for two hours you've already previewed all the parties you're going to go to that night yet it's only 8 PM and you're totally alive charged energetic and ready to go to whichever parties you want to go to Halloween eve
