How far have you driven in one shot?

I recently met up with a friend from college and we were reminiscing (as mid/late 20s do when we dream of the freedom of college again) about stupid college stuff. My friend interned out in San Diego the summer before his senior year and stopped in Vegas on the way back. Then, on a solo trip he left Vegas and drove straight through until Geneva, NY only to arrive 41 hours later. He only stopped for fuel, coffee and sugar. He said he didn't remember much of it now but can remember after passing through some mid-america state he thought he was driving down hill the rest of the way.

We figure there are very few people out there that have gone this long in one drive, but I think OOT would be a good place to start. Although, this thread was ironic to find today. The isolation bit is similar, car vs. apt.

Any other long hauls out there?
