"Sidewalk Puzzle" was one of the two challenging caches of the day. It's misrated and I'm sure the difficulty is higher than 1. The log book is inside a maze puzzle box (it actually looks the same as the one in the linked video) and you have to guide a ball through a maze to open a spring-loaded door. However, I had an idea and realized that I could use a magnet to guide the ball through the maze. So I didn't need a whole lot of dexterity! That cut the puzzle time down to a few minutes of trial and error. The other challenging one was "Wise Guys - Fishing for clues". Actually, since I knew what to do, the real challenge was untangling the fishing line to get enough length to work with. I've seen this kind of hide in Virginia Beach before. Basically, the magnet is on the cache and the "bait" is something metal that you lower to the cache with the fishing line. It took me only one try to get it once I had the fishing line straightened out.
Sunday was more of a mop-up operation. I noticed that there were enough new geocaches around West Chester to make a day of it. I also went to West Goshen, Exton, and Downingtown. There were some good puzzles and also some navigation challenges where I had to use aerial photos to figure out how to get to caches on unmapped roads. "There's a right way and a wrong way.." was one of those. The "wrong way" would be to wade across a river, so it's a good thing I checked the aerial photo before attempting that! "American "Pack" It In" was another one, although I wouldn't fault the Nuvi map for not covering this spot since it's inside an industrial park.
