Wow, Shelly, 2 weeks!!!!! Today I'll be one of the first to say..........
I'm so sorry to hear that your DH will have to have surgery. But at least you have answers now, and he's not worrying about what it could be during your trip. Nothing's worse than imagining what might be wrong. And a hernia is something that is fixable with surgery, so it could definitely be worse. Did his doctors give him anything for pain in the meantime, or will Tylenol/Advil be good enough? He should milk this for all it's worth. Porters, bellhops, valets, the whole nine yards.

Nothing strenuous for a week! Maybe you could get him an
ECV and get to the front of all the lines! Somehow I don't think your DH would go for that. Anyway, I hope he feels great and hardly notices anything during the trip. Thank heavens you don't have to cancel!
Yes, my DS is having a wonderful time in San Francisco. He decided after being there for just a couple of hours that he isn't coming home. I asked him how he came to that decision so quickly and he said that the city was beautiful, his cousin's place was awesome, and the weather was fantastic. (I can understand the weather part. He went from upper 90's and humidity to highs in the 60's) He has a tendency to jump into big ideas, though.

Not long ago it was Colorado he wanted to move to.
Hey, I could have called him Mt. Drew!!
