Just dropped off the load I brought down, answer appears to be no. Basically what they want is for people to not just appear with random aid/crews, they want you to go through their system and notify them that you're coming, what you're bringing, who is coming, when you expect to be there, etc. In the early aftermath it was quite understandable for people to just flow in and start doing something or dropping things off but they're running into problems where they have far too much of certain items, not enough of other items and nowhere good to store some of these items and quite possibly no good way to distribute them to the people who need them. The county I live in [and work for, in Ohio that's all I'm gonna PL] set everything up for me, all I had to do was take the trailer to them, but they're asking that people make arrangements ahead of time at this point in the recovery process.
Likewise if you get too many people in one place, it's going to be a clusterfuck especially given how weak infrastructure is in that region currently. I talked to a few people down there and nobody was turned away if they made arrangements. They are also trying to keep potential looters and lookie-loos out of the area for obvious reasons. It's already a bit of a clusterfuck on the few interstates that let you get to the staging areas, I was essentially part of a convoy for a while and traffic on I-77 near Charlotte was a fucking mess, but once you actually get to the staging area it's all business and pretty quick. They've got National Guard and volunteers [from Red Cross or Samaritan's Purse and quite a few locals] working on offloading and getting things ready to move further up to the people who need supplies. For the first few days it was all hands on deck, show up and start doing something or bring whatever you've got but they're trying to organize it more now.
Also people apparently keep bringing expired food which is fucked up, I get wanting to clean out your pantry and help a good cause but nobody [not even people who had their house destroyed in a flood] wants to eat green beans that expired in 1997. Well, maybe Steve1989MREinfo does, but few others do. From what I heard the main priorities are water [basically nobody in that entire area has water flowing to their home currently], hygiene items, medications, bedding materials, batteries, feminine hygiene products, etc. Also pet food is an overlooked one people don't consider. Cleaning supplies also. Obviously if you're going to bring or send donations try to check and see what is actually needed but those are the items I heard personally being brought up a lot.
I didn't even get close to the true core of where the real damage is but there are a shit-ton of trees down just about everywhere, most of the roads [aside from the obvious ones which were totally washed out] are now clear of debris but obviously I didn't want to get too close since I'd just be getting in the way.
