Kansas City, Memorial Day weekend: I'm now planning to return to ConQuesT for the first time in several years. It'll be a car trip (since it's a lot more convenient to have the car, and it's definitely within easy driving distance). Don't know the exact days yet -- I'll be driving back on Monday, but I haven't decided if I'll be driving Thursday or Friday yet.
Houston, sometime in June: I don't know the exact date yet, but this will be a weekend flight. I suppose it's theoretically possible (but unlikely) that it will pre-empt the above trip, but I seriously doubt it'll be that early. I'm not going to say what it's all about, since I've been sworn to secrecy, but it'll be cool.
Germany for the World Cup: well, I'd wanted to go, but no way in hell it's going to happen at this point. Ah, well. At least I have TV to watch the games on again.
Los Angeles (well, Anaheim), Labor Day weekend (or thereabouts): the World Science Fiction convention. It'll be the first WorldCon I've attended since Millenium Philcon back in 2001; there are several reasons I want to make it, but the bottom line is that it should be fun, despite being in LA (it took various factors to overcome that unfortunate fact).
San Francisco (and Oakland and San Mateo and maybe Gilroy and Monterray): I've been wanting to make it back out there for a while, and while it may or may not happen, there's a couple possible scenarios. I might make it out for the Gilroy Garlic Festival in late July (I'd been meaning to visit during the festival for a while now), or it might end up being a side leg of a WorldCon trip a month after than. It's hard to say how that will turn out.
Japan: well, I'd like to go, but don't have anything solid here. I could probably afford a trip late in the year sometime, though.
