With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 3rd day we visited Canada and met some lovely people at our own Meet & Greet Event.
In Murrayville we drove into a quiet residential area for a cache that had to hang in a tree. Then we took a look at the old pump house from 1911. With a bottle and a stopwatch we calculated how many liters per minute flowed out of the pipe and then we calculated the height difference with the top of the hill.
Thanks and cheers!
