Dear Mohammad,
thank you, nearly everything is nice with me.
I am thinking of going to Iran in beginning of December, but I am afraid about weather (snow???) and to get a visa!
I am also thinking of going to Namibia, but it may be very hot (up to 50°C).
But maybe I will get a cheap flight to Teheran, then bus to Isfahan, by bike Isfahan ---> Yazd ---> Shiraz, Persepolis und back by bus.
Did you think about transportation of your bike by lorry to Teheran? Here in Hamburg very often are vans from Iran...
Best regards,
Gerald
