Just a little more on your Garmin GPS... I have a similar unit loaded with the US Recreational Lakes CD, which is very nice for the lake. But, if you want your GPS to be even better, go to
www.bizer.com and click on the GPS page. There, Bizer sells a waypoint file you can download into your Garmin GPS that will add the lighted markers to your map. I find this incredibly useful.
And, I always keep my Bizer chart on hand too.
