If you you ever you go to the Exeter Chiefs rugby ground, just take a look at the four foodlight towers in each corner of the ground and you will see a piece of bare copper lightning conductor on top of the concrete base. I would ask you to stand on top of this cable and to ask yourself: I wonder what would happen to me in the event lightning were to strike this tower now?
The answer is you would most certainly be killed along with any other person(s) within 3metres of those flood-light towers. Don't take my word for it, ask a Lightning Protection Expert. Ditto for the bridge and other locations in the Stadium.
You don't need to be Einstein to work it out and just for good measure, what if it starts to rain also?
