The north side speed trail isn't as straightforward as the south side. The canal road isn't continuous so this cache series is actually in three parts. I started over at Fort Dupont near Delaware City and did C&D 138 down to 128. Then I drove to the second entry point and did C&D 127 down to 82. Then I used a secret short cut to leave the second stretch and drive to the third stretch, where I did C&D 81 down to 56.
All but a handful of geocaches could be found in a second or two of looking since the placement methods were generally the same. Only a few were placed in a nonstandard manner so I had to look around for a bit. As I recall, only one of the 83 had coordinates that were somewhat off. The GPS stayed in the car most of this trip because I could guess the hiding spot nearly every time before I got there. By this time too, I've had a lot of practice stopping and getting out of and into the car every 0.1 of a mile, so I took a bit less time per geocache this round and finished the whole lot in 2.5 hours. The biggest time waster was driving between the 3 sections. The road construction detour in Delaware City didn't help either. All in all, it was an evening of entertainment, just like the first C&D speed trail.
