My friend Steve had a fun idea: ride our bikes from our home to BART, go into SF, and then bike around the city (literally around the WHOLE city) while stopping at our favorite breweries and bakeries. It all worked out according to plan -- all 25 miles -- until the ride down the hill to Ocean Beach where my bike's front fork broke and my tire dislodged, luckily after the fast downhill section. That was a close call. But I was able to fix the bike enough to keep on peddling and make our way back home around 4pm.
