Glad you posted that, Steelernation. One of the concerns I've had is that people so often hear "electricity takes the shortest path to ground" and tend to believe that it means that if they're not the shortest path that the lightning isn't likely to be a risk.
Some amount of it will take every path available to it to ground...how much depends on how much resistance that path offers...the more resistance, the lower the amount of current that will take that path.
With lightning...even a "small amount" is well over what's lethal for people a LOT of times.
When that lightning hit your generator...think about how much went through the ground rod (the majority)...then how much went through each leg available...and how many of those were less resistance than the path that went through you and the other guys in the tent? Other pieces of equipment probably also had ground rods, offering better paths.
Had it been much more than the relatively miniscule amount that traveled into your tent via the light cords...it could have been MUCH worse.
I'm not saying get out of your hammock in a storm...but I am saying that really there's hardly any true "safe place" in the piney woods during a thunderstorm...including a hammock.
