My university is going on a trip to Germany in April. If it weren't $2400 per person and doing all the same things I did when I was there, I'd totally consider it.
Check this out for more information about the Reformation and Lutherland tour. It's pretty cool that they're going to Prague (LOVE Prague!) and Dresden. I wish I had gone to Dresden while I was there, but it never really happened. I think my friends and I tried once, but somehow we ended up on the wrong train in the middle of nowhere. Not our brightest moment, that's for sure. :)
Anyway, seeing this trip makes me even more excited to go in a year and a half. The anticipation is half the fun!
