drawn to a metal flash and how safe trees for shelter?

If you compare very good electrical insulators, such as dry wood or dry concrete, metal surfaces, it is clear that the more the lightning strikes in the metal surfaces. But the flash is as common as metals also less conductive materials such as wet wood or wet masonry. The same applies to the - compared with poorly conducting metals, compared with well-conducting timber - the body of humans and animals. For this reason, for people in a meadow, the same risk of being struck by lightning, like a metal pole for the same place. Recover metals as good conductors, however, the additional risk that the flash power over long Routes forward. So you should stay away from thunderstorms in the open air of pasture fences, metal railings, or in any case.
certainly know all the old saying: Book shall seek You, You shall avoid oaks. It is unfortunately a myth that book are safer than oak or willow. Certain tree species exert on lightning no special appeal. The same applies to specific geological conditions - such as mining and water veins or rock with natural radioactive radiation.
Science evaluates worldwide for decades, stats, which have shown that in addition to regions with different storm frequency does not narrow areas - so-called 'flash' Nests - There, in which lightning strike preferred. However
be made free-standing trees or tree groups, particularly with far superior branches, relatively frequently by lightning.
