Great stuff mate, that guy you met that runs a hostel in Derry. I stayed in his hostel in February... small world hey, and I sat in the front room with him while he explained how he made money on the races to this other girl that was staying there.
The great adventure will only get better once you head into Eastern Europe... you will save heaps of money down there and there is awesome riding in Romania/Bulgaria. Be sure to check out RTWDougs motocamp - google motosapiens bulgaria. When you are there, ask him about the spaceship monument, called Bazludja, or something, it's the coolest thing I have seen in all of Europe. Shipka pass and the Transfagarasan roads are must do's IMO.
