I'd suggest you contact a school that gives primary in a taildragger
and ask them where/how they get insurance. Here are two places
I've flown and I believe that they both give primary instruction
on their taildraggers.
Sport Aviation, Van Sant www.vansantairport.com
Sunrise Aviation, John Wayne Airport, CA www.sunrise-aviation.com

I also know of two places in Canada that gives primary in a taildragger
and
one that gives primary on floatplanes (that switch to skiis in the
winter).
If you want the names of these, just email me. (The Canadian insurance
situation is a little different, but not much w.r.t. hull coverage.)

I think the answer is that is still possible, but not easy.

Good luck with it, rick
