The opposite has happened too. In reading the logbook, I noticed that some letterboxers found a geocache in Washington Crossing Park (Pennsylvania side) by accident. They wrote a pretty good log about it in the logbook but I don't remember if they signed up for geocaching after the discovery.
In addition, there are some caches on Long Island that function both as letterboxes and geocaches. There are also some letterboxing-style geocaches that only contain a stamp and a logbook. Clearly, there is potential for a lot of crossover between the two sports.
On to today's adventure... It's getting to the point where the caches I'd like to find are 30-40 miles apart. Such is life for the obsessed. Still, I managed to cram in 7 of them today going down the Jersey Shore. The first two caches were closer to home in Union and Middlesex Counties.
Then it was a long drive down Route 18 and the parkway to Island Beach State Park for the next cache. After that, it was time to go to Long Beach Island for the next cache. Those two caches were only 10 miles apart as the crow flies but ironically, the driving distance from one to the other was over 40 miles! Since there wasn't a bridge connecting the barrier islands, I had to go all the way back to out to the parkway just to get to the next one. Oi!
The next two were in Weymouth, a quick trip up Route 322, and then I headed down US-30 to Brigantine for the last one, a virtual cache. The journey home took a mere 2.5 hours. Heavy northbound traffic did not help. Also, there was a big accident in the Union County stretch of the parkway and way too many folks who'd stare at the accident scene rather than drive.
Overall, it was a good day of caching. Next week, the big trip to... ?
