In planning for all of our upcoming trips, I ran across an amazing Google Maps Mashup:
magnalox - magnificent GPS logs and annotated tracks
You can upload GPS logs and make interactive animations from those GPS logs. Many people use it for hiking, biking, etc. There is a 'motoring' section, I'm going to try to make an Off Roading section. I was kind of inspired by a real-time BAJA 1000 tracking site. This site is VERY cool - it could be used to add REAL value to many of our trip reports.
What do you all think?
