Briefing Dilemma

There are days (like today) where the idea is just to fly the airplane. No
specific destination, but if something looks interesting on the ground, or
if I need a Diet Coke or feel the need to unload one, I may land at any of a
dozen nearby airfields... How do you explain this to a FSS briefer? Here's
the discussion I had with the FSS this morning (more or less):

Me to the Briefer: Good Morning, I'll be flying N46KB an Experimental RV-6
today, VFR. Departing at 9:00 local, returning by 3:00 PM, Flying over
North Georgia and East Alabama. Requesting Standard Briefing...

Briefer: What is your destination and cruise altitude?

Me: I don't really have either one. I'm just going flying.

Briefer: I need an altitude so I can provide winds aloft.

Me: I don't really need winds aloft.

Briefer getting frustrated: But it only takes a second. How about 3 & 6k
ft?

Me: I don't really need the information, but go ahead.

Briefer..... Blah, blah, blah at 3 and 6..

Briefer: Also, I need your destination...

And this continued for the next five minutes....

Is there a way to escape this? What I really needed was "VFR projected over
that area all day long, No TFR's or Notams, surface winds out of the NE 10
knots. Have a nice day."
