Lake Ouachita is the largest, it's connected by damn to Lake Hamilton (no offense to those who love it, but it's a crummy over crowded lake with too many homes and rude boaters for my taste), which is in turn connected to a small little lake called Catherine. South of that is one of my favorite lakes DeGray Lake. I had my first sailboat, a 1982 Catalina 25 named S/V Lucky Star, there for 7 years at Iron Mountain Marina and enjoyed the company of the Iron Mountain Yacht Club.
We launched from Brady Mountain Resort's Corp owned boat ramp. Low day rates, plenty of parking and space to set up our rig. Restrooms and a launching dock make the job a little easier. Although we did encounter a few unruly power boaters, most there were friendly and very interested in seeing a little sailboat!
Once out on the water we motored out to discover very little wind, but my iPhone app "Sailflow" said it was coming later in the afternoon and this was a good time to teach the crew a bit more about the boat, sailing and tell them stories of growing up coming to the lake.
