As for my so-called 'most daring thing', the first choice would be dressing up at work and almost being caught.
A few years ago I worked in a bodyshop with a bunch of rednecks and did side work after hours on site. Went in one afternoon and dressed from the neck down minus make-up.
Well all was fine and I was cleaning and putting tools away when the fence jingled letting me know someone was approaching. Looking around the corner my heart stopped, the painter had shown up to do his side work giving me only a minute to switch back before he saw me! It was scary to think what would have happened if he had seen me and told the boss, however I am a very fast dresser when it's an emergency.
I have gotten dressed up complete, with my own hair (beyond the shoulders) and taken many drives. One occasion lasted three hours, covering my whole county. My car is very easy to recognize by my friends so I tried to avoid some areas on my cruise. Stopping at busy intersections I felt as if they were all staring at me. Maybe they were, but I was so excited to be out that it didn't matter. Like many of you out there I love the rush!
