If you are concerned about drowning as you drive around town, you could follow this motorcyclist’s example and strap life jackets to either side of your body.
Cybele and I spotted him (?) on Santa Monica Blvd yesterday, but I forgot to post the photo until just now. I’m glad I was able to get my camera out before he zoomed away between lanes. Someone needs to explain to this guy that life jackets only help if you’re being reckless in the water.
