At customs, a border official actually told us in advance what the entry procedures were, how much each formality cost and in what order we had to do things. An amazing change from getting into Turkey and Syria. It was fairly uneventful, they even had computers versus the old log books used at the Syrian border.
Jordan has proven to be a better place to ride around in than Syria. Instead of long stretches of boring roads with barely a turn, surrounded by desert/wasteland, Jordan is a bit lusher and greener. Also, we stuck mostly to the King's Highway, a secondary road running along a higher elevation than two later and faster routes, east and west of the King's Highway. As in Turkey and Syria, "tourist price" is something to be battled everywhere, but after a while you develop a strategy that seems to work. When buying something, pay with an unlikely small amount of money and act as if that's what you've always paid. In a lot of cases you even get change. That's how I found out a 125 cl bottle of Coca Cola actually can be bought for 10 Piastres (1/10 of a Jordanian Dinar) versus the 25 Pisatres we were charged initially. At the time of our visit, a JD was worth about 1.39 USD.
