Don't wander too far off the beaten path while on your quest, even the local police are some shady cats in those parts.Stay safe and Good Luck with the good stuff.
I brought my own last year when I went to Mazatlan. I put some kief in gel caps even though my bag reeked I didnt get hassled. We flew into Guadalajara the drove to Tequila then to Mazatlan, it was a great trip but I'll never drive around again, scary roads, expensive tolls, spent over 100 USD in tolls to go just over 200 miles.
