getting mulch from the dump ?

[terracore]

Thank you in advance for any help that you can provide. I'm going to go fetch my first pickup load of dump mulch. Can somebody who has been through the process explain this to a newbie and walk me through the process? I know its more complicated than showing up and getting loaded up with mulch. I understand the vehicle has to be weighed? Are their days/times when they load for you? Anything else I need to know? Best practices? Thanks again.
