Chris, I hope everything gets better with your dad. If it would help, check with the hospital to see if they provide facilities for overnight stays or if they are contracted with a hotel to do that. I know the going back and forth can be a real strain and this helps somewhat.
As far as the subject of the thread...I'm not sure I'm really entitled to comment on this since there have only been a few rush threads with ASA in them and it was at schools where they are a more popular chapter. Nothing anyone has said about them has offended me because they've tempered any negatives with a positive. But if I had to read multiple times multiple bad things about my sisters, I might be upset too.
If you want to be completely blunt - fine. But either don't reveal the houses at all, or don't be surprised if when you do people are hurt. I was going to go on but OTW said it better than me.
