Thank you for the reply MMAL, I did previously read the thread about the new rules...was glad I did as well, a gentlemen going with me was planing on packing in a duffel bag similar to the blue bags.
We are planing on purchasing most all the supplies once we arrive in Port Elizabeth so I'll be packing them in my suitcase till then.
We're looking forward to the adventure, we're planning on purchasing all the items you listed above as well as medical supplies. If anyone has used these previously and found things others haven't thought of that are needed or items that you look back and wished you'd purchased please chime in.
