Types Of Venomous Snakes In My Area

So I have been looking fore snakes for a while and to my surprise I found a big snake when I was headed back home. so I was wondering what species of venomous snakes that are in your area so feel free to converse.
by the way The species of venomous snakes that are common in my area Is the Prairie Rattlesnake, Southern Pacific Rattlesnake, and Northern Pacific Rattlesnake Pit Vipers are cool.

We’ve only got two here in the Mid Atlantic, and I’ve only ever seen one (Eastern copperhead) in captivity. Never laid eyes on a Timber rattlesnake, but according to iNaturalist, people see them all the time in the Appalachians: https://www.inaturalist.org/observations?taxon_id=30746
