I was unable to find anything out about this refuge. There was an Aldo Rotundo living in Rehoboth who passed away in 1997, but the obituary only states that he was an avid golfer.
Anyway, this cache should be an easy one to find when you are motoring from Swansea to Seekonk, or back the other way. It's about as close to a Park and Grab as you can get while still having to exit the car.
The container is a nano (gasp!) so bring whatever tools you need to tweeze out the log, but I have a feeling that you will know it when you find it...
