Don't know what's up with these lately. Third one past few weeks. All on the carport in the same place. Couldn't chance it getting away with all the kids around.
You might have a rodent issue that has gone undetected. Try setting some mouse traps around your carport area and see if you snag any. Having that many snakes in the same area means there's a food source they keep going to. Just my opinion for what it's worth.
If there have been that many around, there is DEFINITELY a large food source bringing them there. Get that taken care of, cause thee are plenty more where that one came from.
Big beautiful Timber Rattler. Let me know if any more like that show up!
