Huge M*A*S*H nerd here - since it first aired. Followed it until the end and never missed an episode. I like all 11 years, but I most definitely prefer the years when Mr. Gelbart was involved. I also have the series on DVD and watch one or two episodes almost every day. Great way to unwind after work - glass of red and an hour at the 4077th.
Rest in peace, sir. My world is richer because of you.
*edit*
By coincidence, two weeks ago I finalized plans with a friend of mine to hike out to the old M*A*S*H filming location in the Santa Monica Mountains next month.
