Pat,
Assuming we don't see any additional snow/cold (which doesn't seem to be the case based on the 10 day forecast), I think we might see lower end publics opening by the weekend of March 16-18. I think we'd see more places open the following weekend, but I'm not holding my breath on private clubs being open then.
If I had to put my $5 down, I'd guess that we'll see some privates opening around the 28th or 29th.
Two years ago, pretty much every club was open the last weekend of March. For many clubs, that was earlier than they had ever opened in the past. I hope that will be the case this year.
