"Hardtop" is a kind of car...but I have heard of "blacktop".

I thought "blacktop" was asphalt. "Hardtop" is gray, on account of the gravel rolled into the tar.

That's funny -- I thought it was the war to hold the Union together, and secondarily to free the slaves.

I haven't seen that yet, except for tar and chip or whatever they call that. Actually I knew of one road that when paved it must have had way too much tar and not enough stone. On some of the hotter summer days they would coat it with stone but I don't recall if they rolled it or let the cars do the work. As far as I know they were still adding stone after 6 or 7 years and it was still turning somewhat liquid on the hottest days.
