That park is a known distance from my house... and the ped measured the distance pretty accurately (25 miles).
So last year when I convinceed myself I really didn't ride 40 miles one time... (I thought maybe it was 40 km... from Ron's guess here).... I must have actually ridden the full 40 miles.... hmmmmmmm
Oh well... good to know.. and my gas mileage estimates just went up 50%... lol ...
