DUNNING, Neb. (AP) _ The weather may be iffy, but about 600 bicyclists participating in this year's Bike Ride Across Nebraska seem determined to keep on truckin'. The weeklong bike ride got underway Sunday in Callaway in soggy conditions, following overnight storms, before breaking in Dunning. Fred Jalass has participated in the ride in some way each year since 1986. He says BRAN participants are used to bad weather. There was a tornado when the group camped in Loup City in 1997. Two year before, cyclists rode through a June snowstorm, emptying hardware stores of gloves between Creighton and Ponca. The event this year has drawn participants from across Nebraska, Alabama, Texas and Missouri, and as far away as Canada. The ride ends Saturday in Yutan, after cyclists make the 454 mile trek throughout the eastern part of the state.
