186 is nothing, #180 will do you in. I have ridden it twice in the last couple of days and it sucks scissors.
Loaded with kamikaze loco Central Americans now towing two cars behind pick up trucks in convoys of up to a dozen. A massive number of double truck trailers and the tarmac is in total shit condition.
You can look at the ass end of a truck for a couple of days or you can ride empty and beautiful mountain roads with fresh air and incredible views.
Tough choice LOL!
