Be aware that the loop to the north of Hwy84 on the west end of the bridge is closed to non-hunters from some time in Oct/Nov until some time in January. There is a sign on the west access point with the exact dates. Last I looked there is none at the east access point. No fun arguing with people with guns ;-) The rest of the year that loop is great.
