Traffic was pretty heavy on I-78, but I discovered that it was mostly due to the toll just past the bridge over the Delaware River.
Did the Williams' Walk geocache at the Williams Township Municipal Park. It was actually surprisingly easy, once I found the trailhead, of course. (Silly me. I didn't read the cache page, which had the trailhead info. :) )
Then I went to lupine_fox's and soma_cat's place for the meet. Then our group of 15 went to the nearby Chinese/Japanese restaurant for dinner. The food was pretty good and prices were just about the same as prices in my area. So overall, it was good. Had to leave after dinner to get home at a reasonable time but I made a stop at the Quakertown Wawa store on my way back.
