I'm starting to have second thoughts about jumping my dirt bike on my 58th birthday. I did some calculations and the toy is 4 inches long and I'm going to need 3 inches on each side of it. I took several hours to add all the numbers up and it came to a grand total of 10 inches. I'm not too worried about my dirt bike even though it's getting old....turning 20 this year. But I am worried about making a jump that long. I mean, what happens if I get 5 inches into the jump and get scared. There's no coming back at that point. The pressure I'm stating to feel is probably what Evil Knieval felt before he jumped the Snake River Canyon.
