As I mentioned before, I'm going to Spain for the month of April. I've seen a few other people offer to send postcards from their travel destinations, and Spain is a pretty neat destination, and it looks like I'll have plenty of time for filling postcards with long, contemplative rants about deserts, and my inability to speak Spanish, and man am I ever tired and thirsty and irritable, and so on, so why not?
If you want a postcard from me in Spain, send me an email, with a subject line something like "POSTCARD!!!" containing your current physical mailing address and I'll see what I can do.
Er, priority goes to requests from people I actually know. But I'm not really all that picky, I guess. We can always get to know each other by sending postcards back and forth.
