I had an interesting run in with the radar gun a few yrs back,,,
After sharing a few too many christmas beers with a mate at his shop , I left feeling bullet proof, gunning the 'ol shovel up and over the rise in the road , hitting 6,000 rpm in 3rd I noticed a highway patrol car comming towards me, 1/4 mile away, I hit the brakes (brembo's up front) and washed off most of the excess speed before the patrol car went past, but a quick look in the rear view mirror saw his indicator on,,and I waited for the dreaded flashing lights.
Being VERY carefull not to breath on the officer , when he told be I was clocked doing 80 k's in a 50 zone (phew, is that all ? I'm sure I hit 80 mph !)
I muttered something about the erratic driver I was following, and my need to convert mph into kilometers per hour on my "slow old bike" and hadn't noticed my speed, to which he added "if you are unhapply with this ticket, you can contact the dept via letter , and explain why"
I did this, and to my dis-belief, recieved a letter of apology, and a "tear up the ticket" in the mail soon after.
