Cacti in Minnesota, you betcha! Ball cactus is one of three cactus species native to the Land of 10,000 Lakes and grows in crevices of granitic rocks. They are scarce in the state, but you can spot them at Big Stone National Wildlife Refuge. Photo by Mike Budd / @USFWS https://t.co/K37mo9r6if — PolitiTweet.org
