Going to try and get back out to Australia at some point to visit a mate. The plan was to head for Darwin in the summer (ours) but that isn't looking too likely at the moment so it may be Adelaide for Christmas instead.
Other than that (since nothing really happened in 2009):
Ireland – County Clare and back around the North West: Probably March/April for a week or 10 days
Black Forest – a week on the motorbike probably in the summer.
Ireland – Cork – probably another week by motorbike in the summer.
Think that's about it. I would love to get back up to Orkney this year, but I don't see me having the time for that one alas.
