We go to the San Diego Wild Animal Park and have season passes. They require you show the season pass and a photo ID. They told us to just copy our DL and laminate it o the pass. We did that and have had no trouble until a few days back.
We were at an accident site and the CHP needed our ID. When I was getting my DL out he noticed the other one. I explained to him why we had copied it, but it did not amuse him. He told us it is unlawful to copy any State or Federal ID, including passports.
Do not know if he is correct or not but we did anyway with our copied versions.
Just food for thought.
