Hi Andy, sorry not in Iran, just curious though... did you mean get to Pakistan border by end of this month, August? that just gives you a week? or did you mean end of next month? Iran is one big country to cross... i would of thought at least a fortnight would be the quickest crossing time. Regardless, hope you are having a great time in Iran it is one fantastic country to travel in with some great people and interesting places. Iran, Pak and India are by far my favourites and i bet they will be yours too, enjoy.
Some day so soon....
