Did Georgia last year (must post a few pics), thinking of heading back and doing a proper loop back through Russia via Derbent and Astrakhan, then home via Ukraine, with a possible side excursion to Armenia.
Either that or Kyrgz/Tajikistan, but that would be a fly and drive probably.
It just depends on time really, but its currently shaping up for a minimum six week window June/July.
I'm in a funny situation at the moment, I'm really reaching the point where my personal life and ties are virtually extinct, I'm sober and need to do something that doesn't involve horses.
