I did not see this software mentioned here and decided to share. In preparation for US trip I am searching for a good campgrounds US wide atlas in electronic or paper version. There are comprehensive maps available for each state or region but books with US wide coverage don’t have all campgrounds. For example Frommer’s skips on National Forests campgrounds. To see S&T campgrounds I have to zoom in to the point of losing overall views. I found excellent Plugin Pushpin software for Microsoft Streets & Trips.
POI Mega File - pushpin collections for truckers, RVers, and other travelers
The plugin software is intended for RV folks and truckers with public and private campgrounds, rest areas even height clearances and more. I use Streets &Trips (and Autoroute) for the last few years and like it a lot with my GPS equipped HP netbook, but this new software is good.
