What trip planned do you use

I use the Rand McNally Large Scale road atlas, AAA tourbooks, Google maps, etc. For me, the lower-tech (or at least lower-integration) approach seems to work out pretty well. Often the planning is only in rather broad strokes (i.e. destinations and a rough idea of a possible route), with more specific routing and such being figured out on the day of travel.

For weekend trips, often the planning is dictated by what state parks in the area have sites available that look reasonable for my RV...and have hiking trails or whatever available that look reasonable to me.
