I will be driving in to the California line on Route 40. I want to take a little side trip to Lake Havasu City. So to get from there to Lake Arrowhead in February I assume the fastest way would be to go back up to route 40 and follow it to Barstow and then go south on route 247. Right? But what would it be like to take route 62 from Lake Havasu and then eventually go north on 247? Would the roads be bad in the winter? Would the scenery make it worthwhile? (Time is not an issue.) Thank you.
