If you are going to try for the Espanola put-in (I keep meaning to check it out but have not made it yet), you might see if you could leave your vehicle at La Cocina.
La Cocina has great mexican food and is a short walk from the supposed put in. Their parking lot is pretty well lit and a lot of local police and state troopers eat there. You might call them (505-753-3016) and see if it is cool to leave a vehicle in their lot. Either way it is a good place to eat on your way down from Durango (La Cocina Resturant - The Maestas Family has proudly Served Northern New Mexico for 38 years
The Buckman Road put in is more of a sure thing, but with the warm weather expected this weekend the partyers and fishermen will be out.
I am working this weekend so I can't be of help with a shuttle, but let me know if I can help with any local beta.
