you can roll out too elkhorn crossing just west of omaha, we launch from the camping grounds and drop a car off 10-15 min down the way, it takes a couple hours if youre only coastin and drinkin beers
just take the highway like you are goin to valley or fremont (i forget the #) and take a right by the DQ just b4 valley its pretty easy to find
you can always go out to the niabrara
