I am planning a San Francisco - Los Ángeles bike trip next spring. Is it better to do LA to SF or SF to LA? Thanks, regards from Mexico City
Assuming you're riding the Pacific Coast route, North-to-South is clearly the favorite over South-to-North, at least among Crazy Guy on a Bike users. I'm not sure why that is. I'd recommend reading some of those tour diaries to see if they explain the reason.
