My oldest played at this field In 2015 and my middle child started playing baseball at this field also. He said he wanted to place a cache where he plays his games. I remembered there was a weird little bridge located just off the parking lot and I went to check it out. The bridge spans the Mill River and always attracts the kids that aren't playing in the games. It's a cool area for kids to explore but it's loaded with trash.
Please use stealth (the area has a high muggle factor when baseball games are being played) and replace the cache as you found it. The cache is on the bridge and is a magnetic nano so BYOP, replace the log back into the cap of the nano and replace the cache container as you found it. Kids have great eyes for finding things when exploring. Please use caution on and around the bridge so you don't fall into the river. It won't be a pleasant experience as you will see.
The only way to the cache is from Del Carmine Street off Water Street
