Tailwheel instruction is getting harder and harder to find, at least that is the situation in the northwest part of the country. It seems that between the insurance requirements and the prevalence of nosewheel airplanes, it's just less and less common to see many taildraggers. I know there are still strong pockets here and there, and I would guess Alaska would of course have more "than average", but I'm not up on the specifics. It must be scarce in the east, too, as a high-time tailwheel guy I know here gets calls from people as far away as D.C. to ask for instruction when they buy some fancy, high performance pilot-ego-thumper.
Jim (Fireflyr) mentioned the wheel landing as allowing more definite control in the touchdown phase; that is always how it was taught to me, too. The rule they hammer into you ("You gotta FLY the airplane right from the second you move out of the chocks") really is true. It really IS "alive". Tailwinds can get challenging, more so than in a nosewheel. I think the most "interesting" landing I ever had in a large tailwheel was with a quartering tailwind, fairly strong, and not so much landing as "feeling through" that "no-man's-land" during the transition to get the tail down, and then feeling when to add in reverse because it was a short strip. Yeah, reverse... that adds some fun!!!
I can honestly say I'm sure I've taken multiple years off the lives of several instructors in tailwheels.
I'm not happy they were each screaming to get out of the airplane, but, hey, aviation's supposed to be an adventure, right? (Though, I may have boosted parachute sales, come to think of it.)
If I could WISH for a nice little daydream, it would be to have something like a Citabria, or a Husky, and have ALL the good instructors I know show up to give me unlimited instruction. I'm so rusty now that I'm not sure I could FIND the tailwheel, much less keep control of the little devil.
But, it DOES make you work, and makes you a much better pilot, in my humble opinion. I always tell people to go get the endorsement, if they can.
