Formal parking at the lake doesn't meet even a quarter of the demands for space, so people park on the side of the road. Easy. However, I saw approx. 20 vehicles with tickets on them for being 'in the bike lane' when many were barely touching the line. People aren't parked touching the lane because they want to be jerks to bikers, they are parked there because the alternative would be pulling further over into the adjacent ditch.
It is too bad when the people 'responsible for ensuring public safety' are dangerously irrational. —give me a break!
