I want to take a road trip from LA to Seattle this December- January. I have never driven in northern CA/OR and So am not sure what the weather is like that time of year. Can anyone tell me if the driving conditions are okay? I have two toddlers so I really want to be safe. I think Hwy 101 looks like a beautiful drive, but would I-5 be better/ safer? I am really open to a lot of options and would have 2 weeks to make the trip so I won't be in a huge hurry. Also any suggestions of things to see and do would be appreciated.
