tgee, take the first exit after you go over the Edison bridge. Stay to the right towards Bayshore road. (I don't care what the signs say...stay to the right!) At the stop sign (Deans Marathon will be on your left) turn left on Bayshore road. Stay on that road for about 5 miles and the Dempsey Access will be on your right at the top of the hill. You can't miss it! And good luck to you!!
