5:26 pm Since I had dropped my pen at an earlier cache, I had to sign the log with my knife, carving a tiny III II I SM near the edge of the log.
Edited: I just discovered that this was my 900th cache find! I wasn't keeping track, and didn't take a photo like I usually do for milestone caches. It's not so far, so maybe I'll go back some time and take one anyway. The last 100 came very slowly. Only 100 more to go until the big 1K.
