I walked about 19 miles yesterday.
As we approached the Elkhart Lake area, some very loud mosquitos could be heard in the distance. Over the next hour of hiking, it became clear they were racecars at the Elkhart Speedway - amazing how far across the country the sound carries!
After completing the La Budde segment, we altered our roadwalk to the main entrance of the raceway. PapaBear's overwhelming power of suggestion convinced a gate tender to let us visit for free (rather then $30 each) so you can see our route goes right through the facility and out the southern gate. It wound up adding < 1/2 mile. The cars and crews were fun to watch as we strolled through the paddock area. No $3 pepsis for us, though.
We sped through the first 3 miles of the Kettle Moraine forest to meet our ride. Back to Potawatomi for the van and finally to my folks' home around 8:30 for a long day with not many trail miles.
