Anyway, I went from Salem to Gloucester County, east then north, circling Williamstown. It wasn't really that cold once I got used to it, so towards the end of the day, I did try a half-mile round trip walk for "Senner Property". That went pretty well, even if I thought my fingers were going to freeze off before I got back to the car! To be fair, there were a few other geocaches, "Gone Fishin'", "My First Cache", and "Ducky", with a bit of walking. However, it felt much colder walking across an open field area than in a wooded area because of exposure to the wind. That's another factor to take into consideration beyond the terrain rating.
The only geocache I had difficulty with today was Chop-A-Block. According to the cache description, it is in the cache owner's friend's backyard with permission. Fair enough. When I got there, I noticed that the residents were home. So I knocked on the door and asked them if it was okay to look for the geocache in their backyard. They didn't know anything about the geocache! So I left. Given that coordinates may be a bit off, I think it would've been a good idea for the cache owner to provide a street address in the cache description or hint. However, I'd still knock on the door and ask anyway because it doesn't seem proper to just walk right into someone's backyard. On the other hand, if that was the correct house, then we have a problem.
