About a month ago, i flipped my jeep into a nearby lake. all of my gear was inside. the jeep was completely submerged for about an hour before being pulled out. it was just above freezing that day and my gear froze that night than thawed the next morning, then molded. so my question is this: After being underwater for that long, then freezing, then thawing, then molding, is my poison ivy rope still safe to climb with? any input would be greatly appreciated. thanks and Happy Climbing.
