I'm planning a cycle tour between Vancouver and San Diego later this year. This would start in May and take a couple of months with some city stops along the way.
From my initial research it seems most people travel north to south. I'm trying to decide which direction to travel in and in the interest of following the increasing spring temperatures I thought travelling south to north would make sense.
Is anyone aware of any strong reasons such as prevailing winds that the north to south option is most popular?
