How to drive in a straight line for 9 hours (730kms)

Today we did a massive drive all the way from Reno to Las Vegas along the almost straight highway 95 with only dessert and the Sierra Nevadas to look at it was a long drive but we finally made it to Vegas by night and it made it worth the effort as it was everything we had expected and we started by going up the stratosphere to see some amazing views and then the monorail to take the easy views of the strip. We chose to stay at the Sahara as it is one of the few remaining old school themed casino hotels and it is great with all the sultans and camels within. Plus it has a nascar cafe, museum and ride for the car enthusiasts.
