I'm new to this forum so forgive me if this has already been addressed. My wife and I are planning a road trip the first 2 weeks of October. We are going to fly from Va. to Sacramento, rent a car and drive to Yosemite for a few days. Then we are going to drive to the coast for a leisurely drive up the coast and then fly back out of Portland. Our goal is to enjoy as much nature as we can. We will be camping as much as possible so one of my questions is; during that time of year would I need to make reservations at campgrounds? Also, for our drive up the coast, would route 1 or 101 be a better scenic route keeping in mind that we want to visit as many State and National parks as possible along the way? Realizing we only have a limited amount of time, are there certain "must see" places along the way? We will of course have to stay at hotels some of the time so are there certain towns, or more specifically, reasonably priced hotels along the way that could be recommended? I'm new to this so any help is appreciated.
