I found the 7EC4 Citabria close. Try Twitchells, it's mainly a seaplane place but I have seen lots of taildraggers there. Also Pitsfield, ME. The only "school" that I know that has one is Nashua, NH.
Paul Derry, NH KR2 Stretched N7970K What aircraft would you recommend using to get the taildragger endorsement, and where I find a school with one (I'm located in Maine)? Thanks, -Dj
