Something like that. I had to get a bike to the old Denver airport when it was closed to bikes. I went to the first bus of the morning, hour+ before sunrise, told my sad story to the driver, and he let me on the back of the bus. With the understanding that I had to get off if enough people got on or anyone complained. It worked.

I also had two CHP officers get in my face and say I could not use a section of a limited access road. I showed them an official CalTrans map saying I could get on there. Nice seeing them back down.
