ever since our dollar bill was replaced by a large coin, the "Loonie", in 1987, all of my tire cut booting experiences work but I ride with a distinctive "clunk , clunk, clunk"
same in '98 when our two dollar bill was replaced with the larger "Toonie" so it was then "CLUNK CLUNK CLUNK"
and dangit, I never remember to find and cut out some tyvek envelope pieces , every time you mention this I say I should do it....
