I hope you've got a decent job for a while, or more facilities offering you slots. I'd be concerned about getting a good offer like that for a while. Like you said, what center do you hear good things about? Personally, I think of it like this: There's a couple hundred people at a center and I'm SURE that a good handful of them are unhappy people simply because that's the kind of people they are. They'd find something to be unhappy about anywhere. Those people are the ones that usually make the most noise about a place too. It's more often that people assertively complain about something than people assertively praise something. It's the government, it's never going to be peaches and cream.
All this coming from an optimist. I always try looking on the brighter side of things. Plus I got selected for ZDV, so I'm more adament to look for the best of it.
