Take Rt 90 to Rt 7, the Conneaut exit. Head North to Conny. After coming up the big hill, at the third light from the freeway, with the Shell station on the left corner, you will follow the Rt 7 sign to the right. Just past the McDonalds, you will turn left at the light. Follow that all the way to the lake (a couple miles). As you come over the hill down into the harbor basin, turn left into the ramp parking lot. TA DA!
P.S. Snug Harbor bait shop is the last building on the left before you go down the hill into the harbor basin.
