It seems that the rubber on the southwest bike path lighting issue is about to meet the road. Not sure whether it will be happening or not, but I have never heard anybody mention lights like the ones on the Waunona Way/Bridge Road/Lake Monona Bike Path connector. I'm sure many, if not all, of you have ridden around Lake Monona at some point. Perhaps many of you have ridden around it at dusk, dawn, or at night. I know I have.
On this connector, which is between the Yahara River south outlet and formerly Simpson Street, now Lake Point Dr., there are short metal posts with light through amber lenses near the tops of these posts. The path is sufficiently illuminated and I can't imagine nearby human or owl residents have any reason to have a problem with these lights. Have lights like these been considered? If not, could they be? --- Robert F. Nagel, Attorney Law Offices of Robert Nagel [email protected] www.nagel-law.com Thirty on the Square, 10th Floor 30 W.
