Rick Perry on The Road Again…For Mitt Romney

Texas Gov. Rick Perry is dusting off the cowboy boots and hitting the trail this weekend for his once bitter rival Mitt Romney.

Catherine Frazier, a spokesperson for Perry, confirms to ABC News that the Texas governor will campaign for Romney on a two-day western swing through the battleground states of Colorado and Nevada on Sunday and Monday.

On Sunday, Perry, who dropped out of the Republican presidential primary in January, will hold a meet and greet with volunteers in Colorado Springs, Colo., speak to a group of veterans in Pueblo, Colo., and attend a victory rally in Reno, Nev. The following day, Perry will rally supporters in four cities in Nevada - Carson City, Fallon, Fernley, and Yerington

This won't be Perry's first appearance on behalf of Romney. The Texas governor campaigned for Romney in Elko, Nevada in July.

And a bit of a Perry/Romney feud flashback: A year ago today, the two had one of their most heated exchanges during a debate in Las Vegas when Romney grabbed Perry by the shoulder when he tried to quiet the Texas governor as he accused Romney of hiring of illegal immigrants to landscape his home.
