I moved to SoMD about a year ago and got a kayak for the same reason you did. I spent most of the summer last year getting acquainted with area and sampling a little bit of everything from the Shenandoah to the bay. I got to see a lot of water, but I didn't get "dialed in" on anything in particular.. I did however, have a great day with schoolie stripers from a kayak over by Hoopers Island this fall (check out the video:

I am looking forward to the upcoming spring and summer to hit the bay a little more and also work some of the Potomac tribs for bass and snakehead on a fly. I definitely have a lot of work to do this summer to get big stripers, cobia, and reds from the bay!
