This being said, big old nasty mature bucks will move in real nasty weather BECAUSE they feel safe. Most hunters run for cover. I've witnessed this too. Alot of bold what the hell movement during mid day hours in some drinching rain. Those bucks have plans too like us. It's called stratigy.
Had to go at the sportin goods store. There was pee all over seat. Cleaned it with wad of TP. Applied TP for protection from nasty seat. Turned to sit down. The sensor flushed and the powerful vaccume force inhaled my TP. Not fun.
