Thanks to everyone who replied. I appreciate your support. We've been traveling six days now and I only lost my composure once. Trying to negotiate 700 year old cobblestone streets in a wheelchair and the occassional walking with a cane is very challenging. Ramps are hard to find, handicapped signage is non-existent, but the Italian people have been warm and gracious, willing to pitch in to help.
Pacing my activities and controlling pain and fatigue is somedays ok, somedays not. ~lottie
