A surge in last-minute signups has boosted the amount of land enrolled in Minnesota's new walk-in hunting program to 9,751 acres. That means the DNR came within a whisker of getting the 10,000 acres it had hoped to have enrolled for the first year of the three-year pilot program, which pays landowners to provide public hunting access. "We'll start putting signs up Monday (Aug. 22),'' said Marthbeth Block, walk-in coordinator. Hunters can't access the lands until the signs are up, she said. That won't be done by Sept. 1, the mourning dove season opener. "We're shooting to have them all signed by the waterfowl opener,'' Block said. The lands are in 21 counties of southwestern Minnesota. She said the program has been well received by landowners. The DNR wants to enroll 25,000 acres by 2012 and 50,000 acres by 2013. Only walk-in hunting traffic is allowed on enrolled acres, which are not open to trapping, trap shooting, dog training or activities other than hunting. No vehicle traffic is allowed. Parking is along roads or in designated parking areas.
