Welcome
Where bout's in MD? We close to the upper border and like to jaunt down to Inner Harbour every once in a while.
We are with Colonial and are located in PA. We do most of our swimming at Codorus State Park in Hanover, PA. They actually do informal water work almost every other weekend there. That is also where the Colonial Newf Club does most of their water testing. We actually sail there too. So, we try to go down on weekends whenever possible. It is a nice clean lake with a 3-4' visibility range. It serves as a reservoir for Gladfelter paper.
Check the Colonial website. They will have the water work weekend.. without looking I think it is July 25th weekend. The Flowers do a wondeful job with it! I would highly recomend it. It would be great to meet new people too.... lots of newfs there from all over for a whole weekend! There is a campground and cabins (I think) at the lake.
