Yea, don't you need CT for new England

(used to live there long ago).
With that said. I honestly would release it as a single map and create the huge file. You figure we've been releasing the western states and they're all around 175-200mb each. Then people can just use mapsource to select which areas they want/need.
The java uploader here won't have an issue and I have the bandwidth if thats the concern.
On my GPS I load everything I need; all the topos and everything then I don't have to switch really.
