Ha! I knew I'd get lots of stick for missing Central & South America (and I have). However, my reasoning:
1. I need something to look forward to after I've completed this RTW trip, and Alaska to Tierra del Fuego will be my next adventure.
2. I can't speak Spanish and waiting a year or 2 will give me time to learn and make the most out of the experience.
3. I've taken sooooo long in N America, I'll be lucky to make it round with enough money left for the ferry back to the UK (I hear we have a tunnel now?! Ha ha)
4. Vegas is bl**dy good!
You're right about blogs, of course; I'll try and work out how to post some picts on here...
