Oh, yeah. When we lived in San Antonio, Tx back in 1970-71 there was a lady across the street that was bit on her ankle in the driveway while getting into her car. (The area we lived in was being newly developed with housing and the bulldozers kept the Rattlesnakes moving all the time). A doctor just happened to be next door and gave her immediate first aid and got her to the hospital. To make things worse, it turned out that she was ALSO allergic to the anti-venom they gave her. Sheesh ! She almost died, but did recover, fortunately ...
