TPM Goes to 11

OK, this is just too fucking weird: Talking Points Memo has been taken over by Harry Shearer, i.e., the guy who played Derek Smalls in Spinal Tap.

Dublin-London-Dublin?

Looking through the cost of travel for my June trip. I was thinking of taking a side-trip to London after the Ireland tour, but I came upon a small problem: Airfares from London are about $500 more than from Dublin! I'm wondering whether to take the rail/ferry back to Dublin, then fly back to NYC from there. That would be the cheap route -- I'd save about $400 that way -- but I don't welcome the 7-hour trip (assuming the schedules are reliable). Any advice?

(Normally this post would be friend-filtered, like most that discuss personal plans. I'll make this one public, though, to see if I get any info from people I haven't met, or friends without LJ.)
