Narrative:

Departed from ism unaware that temporary control tower was still in use. Called intentions on CTAF frequency, when departing. No conflict or other traffic seen. Departed to southwest. Florida state airfare was conducted at kissimmee airport (ism), fl, over wkend, sat and sun. I flew my airplane into ism on fri, but due to WX, I had to return on mon to pick it up for return to home base. I did not realize temporary ATCT was still in operation and did not receive clearance to depart. Will check NOTAMS more closely for operation dates of temporary ATCT.
