I have received reports that the customs station south of Cborca has been closed and a new facility opened nearer to Sonoyta. Rather strange since its only 3 years old.
I questioned it, and was told at the new facility they referred to it as the pink elephant. I did notice what looked like a new complex under construction last April on the left hand side northbound, near where the old facility used to be. I will find out for sure going north this spring. Probably prudent to check out the old one first, just in case.
