I found a post that said something about someone staying at "3:45 and Esplanade in Illumination Village" so looks like there may have been an unoffical camp, because I don't see it listed on the BM 2011 Map. I do not think it is a deaf camp. You can read more about Illumination Village at their website Illumination Village Website
As for her signing a V instead of a U... could be she is dyslexic (happens to me all the time when I'm fingerspelling, I know those letters aren't even close, but sometimes ur thinking WAY ahead and it makes your fingers spell in the wrong order) OR... she was spelling so fast that you didn't see the U at the correct time she was actually spelling it - which could totally be the case - you can practice fingerspelling here asl.ms
and see how fast the Deaf fingerspell, make sure to click it on Deaf speed and you will see what I'm talking about.
As for ASL camps, I actually rode past one on the way to the Medics with my honey (he had heat exhaustion *without even being in the sun AND he had drank at least 1gal of electrolyte water and 1gal of just reg water the day before, his body just wasn't absorbing it for some reason*)
none the less back to what I was talking bout. The camp had a sign up in red letters that said ASL and when I saw it I perked up and signed to the guy sitting there "nice to meet you" (even tho I was riding by and didn't really get a change to "meet" him) Its typically one of the first things said when first meeting a Deaf person. - - - He looked happily surprised and signed it back. I wrote down the address it was around 4:30 between B and C.
Now as for a hearing person stopping in to say "Hi" - - - can i just say they would LOVE IT!
!!! My experience with Deaf people (and I'm hearing) has always been welcomed with open arms, even when I was just learning and didn't understand the grammatics of ASL and I basically signed English it didn't matter to them. The Deaf community knew I was trying and were always very understanding.
By far the best website for learning ASL on your own is lifeprint.com
this website has lessons and if you just get through the first 3 lessons (make sure to read everything on the site in the lessons especially the History and Deaf Culture, this will give you a better understanding of how to communicate with a Deaf person) you will be able to have a pretty good foundation.
I remember reading something on the lifeprint site that stayed with me and will hopefully help you in your mission in learning. Studies showed it takes "seeing" a sign happen at least 50 times before you recognize it without having to "think" about it. So try not to get to frustrated if you feel like it takes you a good couple of seconds to comprehend a phrase.
Good luck and cheers, hopefully I'll be out there at TTITD next year and maybe we could meet up and practice signing a bit.
Smile, who cares if you don't have all your teeth.
