I was never actually in Envirothon, didn't have the time for it after school However my school has swept the state level competition probably 4+ years in a row now, so the club is pretty iconic at my old HS
I'm not a fan of soils though (my best friend did soils, actually). I was always **** at using the texture triangle and Munsell color charts in class
If I were in Enviro I probably would've done forestry or aquatics
