Yeah I think Toby is talking about kiting in light rain, drizzle etc with high grey clouds, I was being reckless in a storm basically, with low clouds that can chuck a lightning bolt out of nowhere without warning.
Yes, lightning can hit your kite, Benjamin Franklin almost certainly wasn't struck by lightning.
Check it out if you're interested:
Basically lightning will strike the highest most resistant thing in any given area. The highest thing on the shore is definately a big traction kite on the end of 30m lines. If it's wet it will also have a very high resistance and although (contrary to popular belief) water isn't a good conductor unless there's a lot of it (bath or big puddle, for example, if not rain would short the insulation of high tension lines and make pylons live) the wet lines will transmit a ligtning bolt because it's VERY high tension.
There have been reports of people getting earthing shocks like Franklins after flying kite with kevlar lines after storms, probably because the electromagnetic field of the storm builds up an induced charge in the length of conductor.
