Do what you have to do to conserve your energy and stay cool. Whether its a w/c or a rollator, who cares as long as you can get around and have fun. Wear a hat to keep the sun off your head and def do the bandana thing. They also have cooling vests, cooling wrist things, bandanas, etc thru various companies. If these gals are anything like you described, they wont even notice your "wheels". Enjoy yourself!!
