Erling: The rental agreement probably has some fine-print warning about taking it on remote roads. Just be careful, and make sure it has a good spare tire on board.

W-Jim: Sorry to hear you felt so bad. Since you didn't recover quickly on returning to lower altitude, you probably had a bug of some sort. Certainly the altitude added to the problem, but I'm thinking the bug is what made you turn around.

So why no pictures of the flat tire? grin
