The Almeria association often thanks
American Pilgrims on the Camino for its generous support. It has enabled the association to do waymarking (including beautiful stone mojons), conversions of buildings into albergues, and other activities.
As you say, the existence of a motivated local association that really believes in the camino is a gamechanger - They allocate funds to improvements that benefit pilgrims and local communities and they make a little money go a long way. When I see numbers in the "€ x million" range I start to worry about pork barrel projects for the benefit of the construction industry and political bagmen.
If there's one project on the Mozarabe that I'd like a big construction company to take on, it would be the construction of a footbridge over the Rio Burdalo between Yelbes and San Pedro de Merida. Pilgrims today must ford the river (not always possible) or walk a dangerous 4km stretch of road.
Campanario? I wonder if that was the first albergue on the Mozarabe?
