Its funny, in all the years I have gone, I can think of only one person I ever saw puke. Seen plenty of folks hacking up a lung. I think I would never want to be hammered and then get a whiff of nitro. I feel like that is a good chain reaction waiting to happen. The closest I ever came to puking was one year Beckman and Scelzi who were pitted next to each other fired up at the same time and I just so happened to stand in the perfect spot where the wind seemed to swirl and I was hacking something fierce to the point that I was coughing up smoke as I walked away. I learned early on to stand at a point where I can get the eyes watering, the nose running and a little tickle in the throat without getting to big of a nitro hit.
Probably my all-time favorite story was one year I took a buddy of mine for pre-season testing one day. We were 18 and he was your typical macho hard headed 18 year old and he wanted to stand right at the ropes. I told him it will probably be too rough on him and he ended up betting me $10 that he could stand at the rope for an entire Force warmup. This was back when he & Coil started on gas for about 20 seconds and then switched to nitro with a throttle whack. To his credit he stayed at the rope the entire time but the second he clicked it off he was running for the trash can and was close to puking.
