You wore me out, just getting out of Fresno! Relax! Inhale! I hope you won't need oxygen before you get to the airport. Vacations are supposed to RELIEVE stress, not create it! This is an ADVENTURE, alright! Anytime one heads into a country of jungles and volcanoes to backpack around is an amazing adventure.
I'm going to see about "the Toltec Way," it sounds inspirational, but I wonder what it's based upon, since the Toltecs are long gone. They must have handed down their traditions and beliefs by word of mouth, and in their monuments and statuary. They ruled 1,000 years ago in Central Mexico. I recall references to the Toltecs by Carlos Casteneda, but his mind-blowing accounts turned out to be fictional. Best of Luck!
