Marla, a couple of years ago I was backpacking along there, and I stopped for the night close to the LeConte Ranger Station. I walked over to talk to the ranger. As we talked, another guy walked up. He had been expecting some packer service to drop his food resupply there that day at noon, and this was already 6 p.m. and no show. So, the guy was a little worried and a little hungry. He was asking the ranger for advice on what he should do. The ranger didn't have much to say about the mules. However, the ranger said that she had just come on duty for two weeks there at LeConte, and she had just carried in her own food, and that she had a lot that she could share. I just stood there and watched. The ranger proceded to show the backpacker every package of food that she had in her own extra large Bearikade, trying to "sell" him on a handout to get him through the night. Eventually the guy took two packages of something, thanked the ranger, and disappeared. I hope that you don't get caught the same way.
I know a guy who might be interested in carrying in 35 pounds on foot from South Lake, if the price were right. That would depend somewhat on the firmness of your date and how that matched his availability.
