As someone who also has first hand experience with a severe lightning strike (that left one dead and 11 hospitalized) and on a separate occasion saw a lot of people with hair sticking straight up (we ran to our cars before lightning struck that time), I second this. Don't assume you're safe because you're not near a high point. Lightning strikes wherever. And never, ever, ever stand under a tree. They make great conductors, but your body (a sack of salt water) is an even better conductor, so the lightning jumps to you. Last, lightning strikes are one of the cases where CPR can be effective. The body is still well-oxygenatd, but the heart may stop from the shock, so keeping blood circulating can save a life.

One other thing to be aware of, one the injuries that lightning causes is blindness (temporary but possibly lasting a couple of days). Several of those closest to the strike were blinded - it was described to me as a sunburn of the retina, where vision is not restored until the burns heals. That may not be medically accurate, but describes the experience they went through.
