Driving all night

Just got strapped and tarped. Fun fun in 100+ temps. Showered and ready to drive all night. This load goes to Purvis, Ms due monday but i am relaying it to another driver that is on hometime in SoMiss. Laredo to Slidell is 690 miles so i doubt I make it that far by morning but I hope to get close. May get sleepy, I've been up since 6am, but thats truckin' right?
