When I wanted to find the caches placed nearest to the DeLorme Unique and Natural, I used my Garmin Mapsource software. I located the areas on Mapsource and then it was easy. Right click on the area and select " find near caches on geocaching.com ". The search box opens in your browser and lists the caches for you.
If you want to create a new database in GSAK, ( call it lighthouses ) you can check the caches you wish to visit from the Maine caches. One of the default filters in GSAK is user flagged, choose it and the only waypoints that will show are those that were checked. Then select, Database in the tool bar and Move/Copy waypoints. Send them to your new database and then you have listed all of the " must see " finds. All in one place.
Why not live life like it is your last day....instead of pretending to be a member of the Peter Pan Club and believing you will be around forever.
