yeah only rarely have I actualy been aware of myself improving. I was training with two friends (jumpmonkey and rob if I remember right) at a place in DC called six hills, I was working on this really evil underbar that had been pissing me off for 2 or 3 weeks, almost every day I went for at least an hour and tried to get it. This one training session though, we had been there for about 45 minutes and jumpmonkey and rob wanted to go train at the school in our neighborhood, I said "no, wait a minute, I can get it this time I can feel it" then failed miserably again, after 15 more minutes of "No wait guys, I can get it now, I can feel it"....I got it...after all that work I got it, it was absolutely fantastic...then I went back a few days later with a video camera to try and capture it on tape and I couldnt get it! it was the second most aggravating thing to happen in my parkour training.
