I read that you are in good shape, but that isn't it. What I'm concerd with is your safty. Walking along these roads are dangerous. The cars trucks zip a long so fast you could get clipped or worse. Take real good thought to this, we've seen bikes get clocked off the road. take a cab, rent a car ( we all have our favorites) but please don't walk the sides of the streets! plenty of beaches, mountains to workout! My big recommendation is Mr. Brooks service. Good luck, be safe! http://www.info-res.com/wilfredtaxi/
