Proof that you can just point to a place on a map and get there, even if it takes a couple of weeks! 108 hours of travel, 10 buses, hitch hiking across the country with police cars, sleeping on bags of onions in the back of buses, staying in local's gers, plenty of long 13 hour long journeys crammed with 21 other people in a minivan, sleeping in carparks, having my jacket stolen by a random homeless guy, being treated by a sharman, meeting talking goats, natural hot springs, a week long horse trek across the country and plenty of airag (fermented alcoholic horse milk).
