Let me start by saying my prayers are with the families that lost loved ones and all their property in the Chetek Wisconsin tornado yesterday. I have Ultra Legs (a better version of Sea Legs IMO) and the tornado passed less than an 1/8 of a mile from my boat. It didn't move 1 inch. We all know a tornado can tear apart one house and leave the one next door untouched. But I think this eases my mind a bit about the sturdiness of them and their ability to handle wind.
