roadwhore
A roadwhore is a term of endearment used between engineering and technical contract job shoppers. 
These contract personnel travel from job to job, and typically only take the highest paying jobs; however, 
these same personnel have no problem with uprooting and
driving across the country to work frequent, short duration assignments.
"Gary's an old roadwhore; if that new plant contract hits the streets, he'll be on it like a rat on a Cheeto."
