And here is another site that lets you switch between different kinds of charts:http://mapserver.maptech.com/homepage/index.cfm?BPID=MAP0060030900%2C1%2C1%2C0&CFID=49759&CFTOKEN=70410126

This one allows you to keep them on your computer. www.freeboatingcharts.com You submit which ones you want and they send them to you, I keep a small shortcut to access them.

thanks for the info...

I've been looking for something on the canal itself, more detailed than just the general chart that includes the canal, but I haven't found anything -- anyone know of anything out there, free, or available for purchase? I don't like to try new spots because it's a little too hit or miss (though I know what to look for) for an hour and a half drive. I just go to the old standbys to avoid the skunk.
