Handicap accessible climbing areas near Phoenix

Trying to take my AZ family out for a day of climbing and wanted my younger, wheelchair bound sister to be able to watch. Any beta on some roadside or easily accessible areas? Moderate-Easy routes preferred.

Chris- if you can drive to Tucson check crags against humanity on Lemmon. Few places have what you seek to the degree this spot does. That limits it from an aesthetic perspective but for what you want it is perfect. Make a day of it. Tucson has great restaurants. I recommend anello on 6th.
