Normally, I don’t hold court at posh resorts featuring bright-green golf courses. Especially on the Saturday night before Earth Day, I’m liable to seethe loudly about pompous fairways, water waste, lawnmower emissions, and toxic fertilizers, herbicides, pesticides, fungicides, and rodenticides.

I'm looking forward to being a LitQuest author again this year. Please support this fundraiser that promotes literacy in NM on Saturday, April 18th! About 30 NM authors will be there, and we've been asked to bring five "must reads" for the silent auction. My package will include ecological oldies like *A Sand County Almanac* and *Silent Spring* and a new kid on the block, *The Resilient Investor* by former New Mexicans, Hal Brill, Michael Kramer, and Christopher Peck.
