A reader suggested that I stop by Lepcis Magna (aka Leptis Magna, aka Neapolis) while visiting North Africa.
Not a bad idea, but I have seen tons of Roman ruins from England to Pompeii to North Africa, and they're all about the same: an arena, a forum, a bath, a few monuments and lots of columns, etc. The ones in Carthage were cool.
I prefer seeing Greek things, and it seems like it would be a shame to go through life without seeing ancient Egyptian things in situ.
Where I want to poke around, from the Romans, is Ostia.
We posted on a visit to Ostia a few years ago.
