Welcome to the forum! I have no experience whatsoever fishing the Sandy, so I have no specific advice for you. However, when I go to a "new" river I always watch for vehicles parked along the way and stop to check out what is nearby. Also, don't overlook checking in with any bait shops in the area. Hopefully you will find your own secret spot and come back with a great report and some pics of your catch. Good fishing to you!
