If it hadn't been for the fact that I needed to buy a new rear tyre (the fourth so far) I don't think I would've bothered going to Guatemala City - it doesn't have a good reputation and big cities are always a pain to get into and out of. But within the space of 20 minutes I met an off-duty fireman on a Yamaha who gave me a souvenir notepad, a family in a Jeep who gave me a Guatemalan flag and once I'd found a tyre I was led out of town by another biker.
Soon after I crossed 90 degrees west - three-quarters of the way around the world.
I hope the sign doesn't say no changing of motorcycle tyres in the hotel car park,
