Narrative:
We have a new control tower. I mistakenly thought it was closed on weekends. I called the old CTAF frequency and heard no traffic. Believing the area clear, and facing a 2 mi taxi to the other end of the runway, I took off downwind. I saw another aircraft and took evasive action. We cleared by thousands of ft. I called the control tower and reported myself voluntarily.
