My name is Keith Michaud and this is “Letters From Away,” a blog written by a Mainer living outside the comfortable and sane confines of New England. The blog is intended for Mainers, whether they live in the Pine Tree State or beyond, and for anyone who has loved ’em, been baffled by ’em or both. Ayuh, I am “from away.” Worse still, I live on the Left Coast – in California. Enjoy! Or not. Your choice.

Here’s a link to the Better Business Bureau’s landing page on giving to charities. They have suggestions and recommendations to avoid being scammed. Follow the link to a button specifically to giving in wake of the earthquake in Haiti.
