I have NEVER been bored while riding my bike in my life... Sometimes I have wished that I wasn't riding that day, as snow & pouring rain are not welcome on my rides...

EDIT; Oh yea I am not car free so can take my bike or truck and that can make a difference I suppose...
EDIT #2; Oh yea, I never get bored driving either, but then 350HP in a small hatchback is fun, even stop light to stop light...
