What is Safe?:
- Fully enclosed, permanent building
  - Not roofed, but open shelters (like gazebos)
  - Not fabric covered, metal framed pavilions
  - Shelter from the rain is not the same as shelter from lightning
- Hardtop (non-convertible) Vehicles
- "When Thunder Roars, Head Indoors"
- Shelter at first rumble of thunder
- Shelter until 30 mins after last rumble of thunder
- Anything less than the above increases risk.
At a minimum, make all aware of the risk, & what they can do to lessen their own risk individually.
