Winter Biking, Heart Stuff, GIS Work

For those who seem to enjoy pictures related to my bad-weather bike commuting, here's a shot I took of my helmet after riding to Parkside in freezing rain this morning. On days like this, I often ride for stretches on larger, four-lane roads that are well plowed. I plant myself in the middle of the right lane with all my lights on and let people go around. As long as traffic isn't bad enough to override the safety gain.

I got a call back from the neurologist today. After seeing the results of the holter monitor, she's referring me to a cardiologist for sinus bradycardia; a slow but otherwise typical heartbeat. I know numerous folks have expressed that my resting heartbeat of near 40 is not so odd for someone very fit. I appreciate hearing that! But I'm glad to have the chance to talk to a cardiologist about whether the symptoms I'm having are related to my pulse, and whether she feels that I have anything to worry about.

I had a learning experience with GIS yesterday. Two of them, in fact. First, I spent an hour searching the internet in an effort to determine why I was getting an unhelpful error message when trying to generate a particular file. I finally found out that ArcGIS will not allow a leading numeric character there and doesn't tell you. You know, informative error messages are really underrated.
Second, I spent *another* hour or so carefully georeferencing an 1857 map of Kenosha. When I finished and scrolled around to check my fit, I had a realization. The little unlabeled asterisks on the map that I'd never known the meaning of are *actually* section corners and section line mid-points for the PLSS system! Which means that I could actually use them to georeference the map to a modern PLSS layer much more easily than trying to eyeball the hundred-and-fifty-year-old street network. Heh.
