J. Groth 1987 journal 186. Eastern trip, Minnesota to Michigan July 11 I got up and drove through the rain to Duluth, Minn., and then E on Hwy 2 through northern Wisconsin to Wakefield, Michigan. The truck has been "lurching" since about Reno, Nevada, and is getting worse -- have not found the problem -- idles fine, but no power on some uphill climbs. This whole area seems poor for crossbills -- mostly deciduous trees and no cones on the few conifers. I then went E on Hwy. 28 to Kenton, Michigan, where I turned N on a forest road (paved) and drove through the forest to Hwy. 38. I stopped at a low, boggy area about 1/3 of the way. Here I heard evening grosbeaks, but no crossbills -- and the black spruce and tamarack here had no cones. It was intermittently raining with a very dark sky, but not much wind. Once I got to Hwy 38 I went E to L'Anse, where I drove part of the way N toward Skaneateles. I turned in at the L'Anse ballfield and discovered that the truck's differential oil was very low,
