we have been invited to participate in a Memorial Day parade here in Mercer on Saturday May 22nd. line up by the bank at 9:30, the parade starts at 10 a.m. dinner & program to follow. I know that Katie & Mackenzie will be performing at Worlds of Fun Festival of Dance that morning...Can anyone be in the parade? I'd like to let them know...would need a couple of moms, too...
