The Calvary church in St Helena just got back about a week ago from a multi-denominal trip to northern Baja. The group of about 65 had both building teams that built a school (that was badly needed), and a house for a deserving family, while the medical team simultaneously provide free tmt and meds to the very needy population.
They go about this time yearly. I think there might have been some BC folks, too, in the group.
I didn't go along, so I'm light on details. My wife and I "house sat", so a medical couple could go. Light duties like watering and keeping the sugar water flowing for the free loading hummingbirds. Oh, yeah, and checking out the NAPA Valley wineries.....
