We are parked in Marthaville LA tonight ... I-49 out of Shreveport was a little rough at the beginning and smooth as glass about 10 minutes south of Shreveport. 3132 around Shreveport was pretty dicey .. I bottomed out my IRSI seat several times as we hit bumps, sink holes, concrete separations, tank traps, etc. I'd hate to have done that in a plastic rv as there would be a long trail of pieces like some kind of Winnebago branded breadcrumbs behind me.
