There are white signs on the side of the road for every mile you reach. Just past the 27 mile marker there is a memorial on the side of the road,you can't miss it,this is good place to put in and away you go to the 20 mile bridge! That's alot of river to cover so be safe and have a good one.It's a fairly easy drift just stay away from log jams you can get into trouble here.
