i had a flood a few years ago...
in the basement of the home i rented.
i had renters insurance, that covered the replacement costs and repairs of all my gear that was damaged.
anything can happen, at anytime.
if your gear is worth insuring, then insure it.
it's just that simple.
make sure your agent understands what you want.
not market value, but the value of replacement at the dollar figure you set.
you'll pay more for it that way.
but it's all a gamble, eh?
meteorites, and all that........
