Here's the rules from the Rays website:

1. All riders must sign a waiver. Members must present their Ray’s Photo I.D. on each visit. Non-members must sign a waiver on each visit. NOTE: Anyone under 18 without a parent/legal guardian present to sign a waiver must have it witnessed/sealed by notary. NO EXCEPTIONS! Please plan ahead.

2. We are going to start using colored wrist bands at the park. You must wear you wrist band at all times. Season pass holders & members must show I.D. and sign in at the front desk. Please write your wrist band number and an emergency contact phone number for that visit on the sign in sheet.

3. Helmet and gloves required at all times while riding. No exceptions. Elbow guards (recommended) or long sleeve shirt. Knee and shin guards (recommended) or long pant legs.

4. All riders must be 16 and over unless accompanied by a parent or guardian who is also riding. We encourage parents to teach their children to ride. We are not a sitting service. The price for an additional underage rider is $10.00.

5. Riders under 18 must have waiver signed by parent or guardian.

6. No fighting, loitering, spitting, dirty looks, etc.

7. No intentional damaging or tagging of park property. If something breaks, report it to a staff member immediately. Please respect the trail as you would outdoors.
