Narrative:

When departing addison airport to the north on a 100 degree day, I was thinking more about the cooler air at altitude, than the class B airspace above 3000 ft MSL. When I saw on the moving map that I was in class B airspace about 3000 ft (I was at 3300 ft MSL). I immediately descended to 3000 ft. On my way back down the tower advised me to do so also. No problems arose from this error.
