Sunday's trip was to Philadelphia, Northeast Philadelphia, and then Bensalem, Langhorne, and Levittown. It's not my favorite area but enough time has passed that there are lots of new caches around. First, I made a visit to Pier 68, one of the piers in the city that has been turned into a park. Later, there was an ampersand bench at another river view. The Veterans Memorial Park was nice too.
The problem with the Levittown / Oxford Valley area appears to be cache theft. I read the cache logs and noticed a number of notes about caches getting stolen and replaced a bunch of times. I tried to find a bunch of geocaches in that area anyway. Some were still there but I had no idea about the others. I logged my DNFs and by the next day, I saw that the cache owner had archived some of the missing caches. This is not the first time I've seen this problem. Sadly, nothing much can be done except wait for the cache thief to get tired of stealing caches. Thankfully, it seems to be fairly localized to a small area.
