I have done that before, and if you approach it in the spirit of Adventure, you will be OK. Leave yourself plenty of time, bring a cell phone, charger, cash and credit card. You can buy tools and parts as needed along the way. Don't trust the fuel gauge, fill it before you depart and stop and refill it after 100 miles. Check the MPG so you will know your safe range and while you are at the station, grab some snacks and some bottled water, a quart of oil and ATF if so equipped, and give the car a good once over again. Don't forget to check the wipers, the worst time to find out the blades are shot or the motor/linkage is bad is during a deluge when you are trapped in traffic. Have fun and be safe:headbang:
