Thanks, Aggie and Dave.
If you've already sent it out, don't worry about it. We've been out here for several weeks, and we've got mail forwarding (they do forward magazines) until August 10 (a little later than we should have, but it's too complicated to change it at this point), and we'll be at this address until the 14th, then at another address until the 21st. We'll leave a Priority Mail envelope with the front desk at our condo to send back anything that arrives after we've left.
If you haven't sent it out, and wouldn't mind hanging on to it until August 10, that would be great! Then it will arrive in New York and won't be forwarded, and I'll just get it when I get home.
