A homemade key used to open parking meters is a burglarious tool. Perkins v. State, 61 Wis. 2d 341, 212 N.W.2d 141 (1973). It was implausible that the defendant was looking for the home of an acquaintance in order to pick up some artwork while carrying a crowbar, a pair of gloves, and a pair of socks. Hansen v. State, 64 Wis. 2d 541, 219 N.W.2d 246 (1974). Section 939.72(3) does not bar convictions for possession of burglarious tools and burglary arising out of a single transaction. Dumas v.
