EBMUD Checking Permits at Briones Reservoir

To test my ankle I did a loop around Briones Reservoir yesterday. Saw some neat stuff - the goats are out, big gopher snake, woke up a deer sleeping in high grass - but the point of the post is that right as I finished, an EBMUD officer pulled into the Bear Creek staging area and asked to see my permit. In 10 years of running EBMUD trails, that's the first time I'd been asked. When I got mine it was $20 for 3years - I laminated it at the office and carry it with me on trail.
