Fairport Harbor is probably the best one near mentor. It's ten dollars but it's not a bad ramp and typically isn't packed unless it's a super nice day for tubing, skiing, and jet ski's. Just head N-NW 3-3.5 miles until you find "the hump" that goes from 50 ft to 42 ft then back down to 60 feet. The fish are usually in there. You'll see mentor headlands beach and the Fairport lighthouse on shore. Read the last thread on mentor for other info on that area. Good luck!
If all goes well at the airports, I'll be out there ASAP today Saturday.
