Dear Mr. Sergeant, With all great respect for your fishing advice, I read with great interest today’s article on USGS Surveys and went to the site.  Have you ever tried Google Earth to view waterways? It’s a pretty good tool to zoom in especially when you’re looking for grass flats etc. Best wishes and hope to meet you in person (to get some fishing tips)! - Vince Mazzara
Vince: Good point - I use that one frequently, too, and have mentioned it in my column before. The difference on the USGS sight is that you can see the deep water contours, which is of special interest to grouper and snapper fishermen. Tight lines. FS
