[Callers] Dances of the Mormon Trek 1840-1860

Hi all, I have been hired to lead some dancing for a recreation of the Mormon Trek that took place from 1840 to 1860. Apparently they believed in dancing and danced during the trek itself. It would be fun to include any historically accurate (or roughly historically accurate) material that I can. There will be close to 100 dancers mostly teenagers I believe, most or all with no prior experience with traditional dance. Any suggestions for easy dances - circles, sets or maybe contras (although I know better than to expect them to do contras unless we turn the contras into Sicilian circles) would be very welcome. I might even take on a square or two. The dance will take place outside, perhaps under a tent, but I believe without a wooden floor. Your suggestions will be happily danced. Thanks, Rickey Holt, Fremont, NH
