First, and most important: hydrate [“What a Ride,” Your Life]! Bring a refillable water bottle with you to the park, plus a ziplock bag filled with a few quick snacks on which to nibble. Some parks have wheelchairs and personal mobility scooters for rent, which can be helpful on a hot, crowded day. Last, check park maps for first aid stations and don’t hesitate to reach out to park employees should you not feel well. They will usually have EMTs on standby.
