Narrative:

Departed stp after low approach. Stp is only about a mi from msp class B airspace. I was just west, heading south toward D97 about 7 mi south of stp. I accidentally strayed about .2 NM into class B airspace, departed immediately, inside the airspace no more than 30 second to 1 min. Was in contact with stp tower which did not mention this. Considering close proximity of class B airspace, I should pay closer attention to DME in that location.
