Here in the eastern slopes of the rockies, we get wicked ones. I've been in a bowl in the mountains where literally, you could pretty much see continuously by the strikes on the ridges (it was like a strobe light) with constant noise.

I bail out of trips (or get delayed) probably more for threat of lightning in high areas than anything else. I'm not too worried down low, but walking across exposed ridges during one of those is more risk than I will take.

If you're heading into high exposed alpine, top of ridge stuff, stay down if there is lighting threatening, or get down if you get caught out. best is not to get caught out, of course.
