Crouch low, don't lay down if a strike feels imminent due to raised hair and/or tingly sensation.

Tall structures such as towers, trees, buildings, and similar items can draw lightning even before the storm is really evident, so they should be avoided if electrical storms are reported within the geographical area. If caught in an electrical storm, my metal bike is usually leaned against something low (like a wooden fence) while I walk 20 yards away to wait the storm out for a bit. Good luck.
