I rolled around as much as I could to try and position myself to get the cramp to go away. Nothing was working. I decided to go outside and walk around until it went away. The only problem with that plan is I didn't know how to get out of the tent. I gingerly crawl to the zipped entrance of the tent and search for the zipper while trying to hold back tears (when I first wake up I don't have the processing power to compose my manly behaviors, so yes, I was really on the verge of bawling). After groping blindly for about half a minute I find the zipper and get the flap open. What was waiting for me at the end of the tent was another tent opening that was zipped up. This was the rain cover. I felt like screaming in anger/agony/frustration as I start another search for another zipper. This is a puzzle that I did not finish. The pain in my leg intensified and I decided to crawl under the opening of the flaps and out to freedom. I stuck my arms underneath and I drug myself under this staked down fabric. I stood up and walked around for a minute before the cramp went away. I went to the car and grabbed my bottles of water and Power Ade. I drank for five minutes off and on before I sat down and tested out the leg to make sure it was okay to be bent. It was sore but the cramp did not return. So I returned to the tent (through the flap, not via army crawl )and checked the time. 10:42. I wasn't even asleep for two hours... It took almost another hour to get back to sleep.
