A CD with an Aerial and a Topo Map linked to Google Earth would be so much help. Click on the state you want and see all the claims in that state. Zoom into an area you will be in and print out the map to take along..... that book drives me crazy trying to figure out exactly where it is that i want to go...... this could also save on Catalog Costs given an option to purchase dues either way
The CD could be made impossible to copy to protect from piracy and Legal terms put in to protect the club from others.
An App sure would be nice but on the Androids the tiles for the map would have to be imbedded for areas of no signal which takes up a lot of room but iphones are easier to do (I don't have one)
The CD would be great to armchair Prospect for a future outing.
Just a thought
