If I have misplaced my annual pass, can they look it up or do I have to purchase anorher?

Yes give them a call

No, you don't have to purchase another one. They will look you up by name and give you a one day pass for no charge. They will ask for your identification card... Like drivers license, etc.

Yeah I would just call and ask.

I'm sure they can look it up for you. They may charge you for another card though.

Call them
