Sunday Times Teaser 2709 – Around America

By Victor Bryant

The two letter abbreviations for the 51 US States are:

AK AL AR AZ CA CO CT DC DE FL
GA HI IA ID IL IN KS KY LA MA
MD ME MI MN MO MS MT NC ND NE
NH NJ NM NV NY OH OK OR PA RI
SC SD TN TX UT VA VT WA WI WV
WY

I have written different letters once each around a circle in such a way that when any two adjacent letters are read clockwise they form one of the above abbreviations. One of my letters in R and no longer sequence of letters is possible.

What are my letters reading clockwise starting with R?
