OCIA.net drives from Olive Branch, MS to Las Vegas by car to the CES 2007 show. Here's a snip from the first part of their adventure:
"Mapquest calculates the trip to be 1602.61 miles from Olive Branch, MS to Las Vegas, NV which equates to 23 hours, 18 minutes and traveling through eight states. The original plan was to leave out at 8 a.m. Friday morning. Well, that didn't happen as some last minute packing and vehicle maintenance was required. We ended up rolling out around 2:30 p.m. after a quick Burger King lunch. We will be driving straight, only stopping for food and gas (who needs sleep anyway?)."
