Gov. Sarah Palin has been racking up air miles and sending Twitter updates since her surprise announcement five days ago she will resign late this month.

Today, Palin flew to the Interior village of McGrath to sign an obscure bill to extend the termination date of the Board of Veterinary Examiners.

Since Friday, the governor has flown at least 2,300 miles, traveling to some far-flung places even by Alaska standards. She briefly attended in a Fourth of July parade in Juneau. From there, it was off to Dillingham to fish. Then, it was off to the Arctic town of Kotzebue for another bill signing.

Palin also sent several Twitter updates Wednesday. One said, "Today, try this, Act in accordance to your conscience -- risk -- by pursuing larger vision in opposition to popular, powerful pressure."
