LA does not fair well in rare rain

Yesterday D and I tried to commute home during an unexpected and VERY rare rain storm. It normally takes about 30 minutes in the afternoon to get home on surface streets. Not a bad commute. Occasionally I pick D up from work and double back to my office so she can drop me off and I can get in another hour of work before biking home. Yesterday after trying to double back for almost an hour, we gave up and went home. It took us 2 HOURS! 

There were no accidents as far as we could tell on the surface streets, just what felt like every car off the highway and on the surface streets. Mind boggling!
