Ok, here we go. Solitary trees in an otherwise flat landscape or to be avoided, however, groups or similarly sized trees are safe. Makes sense. I was never sure of that one...

AVOID: Avoid water. Avoid all metallic objects. Avoid the high ground. Avoid solitary tall trees. Avoid close contact with others - spread out 15-20 ft. apart. Avoid contact with dissimilar objects (water & land; boat & land; rock & ground; tree & ground). Avoid open spaces.

SEEK: Seek clumps of shrubs or trees of uniform height. Seek ditches, trenches or the low ground. Seek a low, crouching position with feet together with hands on ears to minimize acoujstic shock from thunder.

KEEP: Keep a high level of safety awareness for thirty minutes after the last observed lightning or thunder.
