As a B unit I have found it very difficult to get out of NC and SC; Charleston being the one exception.
I try not deliver into the Spartanburg, Greenville, Charolette area (or any place east of Atlanta on I-85) after Wednesday. Normally, if I am not loaded out of that area by Thursday evening, I will sit there until Monday.
Last night the board for just one carrier showed 3 A units and 14 B units available within a 100 mile radius of Charolette. Also, 12 D units, 7 E units, and 4 F units.
In the final analysis, if your carrier provides you with access to unit positions (real companies do) it will not require a greaat deal of research to quickly determine the areas you need to be positioned in at any given day of the week.
Sticking around in Charolette for 3 days might allow you to see some changes: the weather, fuel prices, different TV programs, new faces, etc. BUT sticking around does not pay the bills.
Information is power...use it to your advantage!
