Snakes are easy. All you have to do is memorize the venomous ones in your state or commonwealth, and leave the rest alone.
Here in my area we have four dangerous ones supposedly - Rattler, Copperhead, Water Moccasin, and Coral. Realistically we never see Coral snakes. Likewise, Rattlers generally leave the area when a human is around. The Copperhead and Cottonmouth are a pain in the neck (or ankle) as they stand their ground and/or are aggressive. So we really only have to know two.
Snakes are wonderful at keeping the varmints down. No reason to dislike all snakes. Now, scorpions......yeck!
