The first Prairie Lindy Exchange (Plex) arrived in Saskatoon from March 11-13, 2005. Soon after, the roaming Lindy Exchange tradition began. Held twice a year (or thereabouts), Plex has also taken place in Calgary, Edmonton, Winnipeg and Minneapolis. Plex 10 will return to Saskatoon for Plex's five year anniversary in March 2010.

Prairie Lindy Exchanges have the reputation for being social exchanges filled with good fun, good times, good dancing and good friends. The Sunday latenights are rumoured to be worth the price of admission alone. Plex started out of the need to bring the prairie lindy scenes together. Since then, Plexes have drawn dancers from all over North America and as far away as Australia.
