Graciela needs a lift to the San Cristóbal de las Casas Dialysis Unit - can you help one day a week?

Graciela has been on dialysis for 4 years and until recently drove to the San Cristóbal de las Casas Dialysis Unit alone. After an eyesight problem, Graciela can no longer drive. Taxis cost more than the family can pay three times a week. We're building a rota of volunteer drivers. Each session is 4 hours, including the trip there and back; most volunteers take one regular day. The journey is about 27 km each way. Graciela is cheerful company. You'd need a car in good condition and a clean driving record. We'll cover your fuel costs, and the family will send you home with homemade food. Please say which day works for you in the comments. Thank you so much.
