mm that hot spots map is a good chart...map, dont know if you can call it a chart if it not supposed to be used for navigational purposes..either way its very helpful
the launch at the end of hall road is a DNR launch, so generally you have to pay 3-5 dollars to launch on a weekend, usually no-one is on site in on the weekday and you ge tin for free( not sure on this particular ramp ), an 8 lane blacktop ramp, loading pier, and large parking lot, and restrooms, the site is closed from 11 p.m. to 4 a.m., the ramp lets you out in anchor bay, and is almost driectly west of the first N. Channel marker
Another one you might consider is the Brandenburg Park DNR BAS, its right down the road on jefferson from the one at the end of hall road, its the same 8 lane blacktop ramp with restrooms, huge parking lot and fishing pier, and picnic area, and a park for the little ones...this one is a little further north on jefferson from hall road, and lets you out right after Anchor bay south of new baltimore, alomst straight west of grassy island
hope this helps a little
*man i must type slow you guys beat meto it lol
