You will get a lot of mocking replies to your post but don't sweat it!
It is cool to go with people you know, however, it's equally as cool (almost MORE fun) to go alone.
My first year I did just as someone else posted here. I read all the information available, read forums, etc. Packed WAY more than I needed, hehe.
I went mostly alone (I did know a girl out there who had given me info and I camped near her and her friends, altho I was technically alone) and had a blast. You can't avoid meeting tons of nice people.
I even had some annoying mishaps. I had purchased a camp stove at a garage sale and planned my food around cooking on it and it broke! So I had to adapt and eat mostly raw/snacks. Lots of hummus and pita bread with veggies, etc. It's just part of the experience, I still ended up being radically self-reliant. I did, however, get invited to a lovely gourmet dinner by some nearby neighbors who saw me riding by on my bike wearing a funky combination of wings, fur and other weird costumey things. They thought it looked neat and hollered at me to come over and eat with them. :D It was a blast!
My second year I went even more alone and ended up meeting my neighbors and joining their camp. Now I have a big group of friends here in the Bay Area (I moved down here from Portland) and a camp/family I will camp with every year!
Don't be afraid to go it alone if that's how it ends up. You will meet amazing people and possibly make lifelong friends. My first two years alone were a GREAT adventure! :) I highly recommend it.
