What mooseTek said! Always! Always! Read the comments!!! It depends on the load, and sometimes your DM can see planner/CSR notes you can't. Some will take loads early, some wont. Some will not allow you on their property early due to parking constraints, or whatever reason... some require lumper fees and other nonsense. Always read the comments. Glad to see you're doing well whoop. Swift has a system, once you figure out what to do and who to talk to to solve problems, life gets easier.
Hit me up with any questions you may have, I'll be glad to lend some advice when and where I can.
In addition, always send the Mac 23 for directions - for both shipper and receiver.
The information in those instructions can sometimes mention important things the load assignment comments leave out.
