Hi Gerard, Great stories, thanks for sharing them! Your second story reminds me a bit of a story that a Linn County birder posted on OBOL back in late 2001, when the whole country was on hyper-alert after the World Trade Center attacks, and there was special attention for reservoirs. For a brief periods (before the American Geophysical Union and others convinced the feds that this was ridiculous and would just cause problems for scientific research), reservoirs and dams were even blotted out on digital maps. Wish I could remember who posted the story, but it had to be someone fairly tall or else the story wouldn't work. Maybe it was Jeff Harding? Or Tom Snetsinger? Whoever it was had his scope set up on Foster Dam, looking for migrant loons, grebes, scoters and the like (in proper taxonomic order, for those days). Up came the local law enforcement dude, to ask what they were looking at. Not completely satisfied with the answer, the cop wanted to see for himself, exactly what the birder was looking at. The problem (this is where height comes into the story) was that the birder was a taller guy, and the cop was a shorter guy. So the cop jumped up and down a few times, trying to verify the birder's story. Who knows what he saw (it's hard to imagine that he saw anything by this method) but I guess the important thing was that he showed some effort. He was also less trusting than the military captain that you encountered in Mexico during the Zapatista period. One good thing to come from this story, though, is that whenever I'm leading some sort of birding trip, I remember to look around the group and set my scope height so it will work for everyone, before I even start to line up birds. The image of that poor cop hopping up and down has never left me. Happy birding, Joel On Tue, 2015-02-03 at 14:33 -0800, Gerard Lillie wrote: > > > ....
