Speaking of Lightning...

...but not the feline version at my house, Jim Smith sends along this peculiar article about a man in Florida struck down by a "bolt from the blue."

Obviously, we've pretty much all heard that expression, and somewhere deep in the crevices of my brain that contain the remnants of all my manly, woodsy, outdoorsy lore, that you could get hit by lightning even if there were no rain clouds nearby, but I never knew that THIS type of lightning was any different from any other sort.

Oddly enough:

[...] Experts said [landscaper David] Canales was killed by a weather phenomenon fittingly called a ''bolt from the blue'' or ''dry lightning'' because it falls from clear, blue skies. [...]

The fair-weather bolts pack a bigger, deadlier punch and form differently.

Most lightning bolts carry a negative charge, but ''bolts from the blue'' have a positive charge, carry as much as 10 times the current, are hotter and last longer.

The bolts normally travel horizontally away from the storm and reach farther than typical lightning, then curve to the ground. [...]

I have a question. Maybe some of your other readers have experience.

Because our carport floor is so slippery under certain humid conditions, Lyman has ordered a kit from U Coat It to provide some texture.

Do any of you have experience with this product?

Possibly so, although it might get a better response in its own entry.

There is a similar product installed on a pedestrian ramp here at our building and it has done well.
