On paper, and the monitor, the idea looks good. My concern is that adjoining states may fall outside of ones home waters. In this local case, many people from Georgia choose to fish in NC a lot and many in NC like to raid the fishery of Tennessee.
Nit-picky I know, but a valid downside to time zones none-the-less.
Lucky for me you asked for feedback and not suggestions!
I have to ask just because I wonder though, is that Ebay thread looked at very much and is it a real resource hog. The reason I ask is that load times on this site have gotten slower and most times the 'back' button function simply reloads the same page. I noticed these small glitches appeared about the same time as the Ebay topic made its appearance.
