Overnight stay in Birmingham?

There is really not much to choose from around Birmingham along your route I-25 is fairly new and not much has been developed at the exits. Oak Mountain SP and Hoover Campground are pretty far out of your way. I know there are some campgrounds by Lake Logan Martin, near Pell City. Don't know much about them, except that you can see them from I-20. Probably OK for an overnight stay if space is available. A lot of these type campgrounds cater to fishermen and fill up on weekends and holidays.

Edit: Looking at reviews, I would probably go with Lakeside Landing, just south of I-20 near Pell City.
