Boquillas del Carmen is a tiny Mexican village across the Rio Grande from within Big Bend National Park. Before 9-11 it was common for park visitors to pay a Mexican guy (yes, he was Mexican) a few bucks for a quick boat ride across the river. The only reason anyone would ever visit this desolate, but scenic place (other than just to say you crossed the river into Mexico) is for a tasty taco lunch and a semi-cold beer while touring the scenery of Big Bend.
The reference photo for this painting was taken decades ago when we actually did cross the river, and our kids rode burros like this one up to the village from the river. The small building in the background was added just to give some perspective on the nearby hills.
