A favorite of mine on the "Sunrise Side" is Harrisville State Park located on the shores of Lake Huron, south of Alpena. It's one of the older SP's but located in a nice area and great for bicycling into town.
Recommended water front sites: 88 (A+), 103 (A), 91, 86, 64, and 58.
Recommended flat interior sites: 144, 79, 98, 95, 45, and 42 (there are other good interior sites as well.
Recommended pull through sites: 4, 6, 7.
