I’m very relaxed out in the wilds.

One of the very few things that worries me is getting caught in a lightning storm.

I have a friend who was struck. Three of the 4 in their group survived.

• find lower ground ➙ and get under uniform tree cover, if possible.
• you can be struck by a storm still 10 miles away
• lightning tends to strike the tallest object on a landscape. It’s not a good idea to stand under a tall tree.
• lightning is not attracted to metal. Lightning is only attracted to 3 things: tall structures, isolated structures, and pointed structures. 
• metal can conduct electricity, which can jump to a tent 10 to 20 feet away. So tent away from taller and/or metal structures like bear poles.
• crouching to get lower is not recommended
• sheltering in a cave not recommended
