Premise: The Lake Wobegon Trails are two paved recreational rail trails in central Minnesota, named after the fictional Lake Wobegon in Garrison Keillor's "Prairie Home Companion". Each trail is marked with mileposts every 0.5 mi , corresponding with the mile markers of the former railroad lines. Snowmobile use is allowed on the trail in winter, conditions permitting.
Hypothesis: Trails are marked with mileposts every half-mile.
