Dog days of summer. A few estate sale companies in my area go entirely dark at this time of the year, and then things pick up again later in August. Our street is a ghost town right now, everyone is at the cottage, etc. It's prime vacation time. I made a few scores during the Guernsey's WW1 and WW2 auction on this very day last year, had the same auction taken place at any other time I'm doubt I would have been able to pick anything up.
Probably Heritage wants to pre-empt EMP (and last year, Morrie's stuff) by having it now. I think Bruce is smarter waiting until later in August.
