Way too fond of many of the modern goodies.
"What happened at the Library at Alexandria? I'd love to read some of those scrolls.
The Constitutional Convention.
A conversation with Archemedes, Ptolomy, any number of Engineers and Philosphers that a lot of modern society grew from.
Watch Edison work, or Tesla.
But just for a visit mind you, life back then was not something I'd want to spend a lot of time becoming used to.
