The current challenge at qaf_challenges (running concurrently on LJ and IJ) is "Weather/Vacation." I wrote for it... but the fics are anonymous for the first few days. Go see if you can find mine -- and you'll have fun looking, too, because there are some terrific stories there!

Here's a hint: My story is about Brian and Justin and they have sex.

I know you're shocked. 

Remember to leave the authors some love. It's what we live for.
