Check out this original race information sheet from way back in The Day. The sheet was written by George Ripley who conceived the Wilderness Classic Race some thirty years ago. Part of the sheet mentions the first annual Pioneer Classic but it also says it's the 2nd annual race on the first page. I assume this is probably from the second race in 1982 and George included the information sheet from the previous year for reference.
Look at the suggested gear checklist which includes a .22 pistol and fishing hook to help gather food along the way.
