From what I have seen: reports of farms having enough high ground for horses or they got their horses out. However, communications are spotty and I suspect that we aren’t hearing from those who remain without cell service or the bandwidth to communicate a worse outcome. Just a guess.
@Montanas_Girl posted a great resource.
Here in central NC, several people are soliciting donations via feed and pet stores. The plan is to load up early this week with supplies and head to the Statesville, NC airport to supply an air drop if allowed. If they are directed elsewhere once in Stateville (seems to be as far west that the general public can travel to) then they will follow emergency personnel orders. This is second hand (according to Facebook) but Moore Equine and Feed Supply alledgedly is setting up a donation account. They can then use funds to arrange with their contact to get supplies to Statesville. This may be the best way people can contribute. Moore Equine can send “a case of vet wrap” or “a pallet of alfalfa cubes” instead of someone donating 3 bags of XYZ obscure feed. Please confirm with all feed stores they have such an account set up…do your diligence when donating.
