In order to conserve on gas, I am eating less beans and other gastrointestinally hazardous foods. Some people don't want blood for oil; in my case, it's "no salsa for me".
Seriously, I'm occasionally making a calm case for the American right of self-protection and keeping an eye on the Franco-German efforts to split the Atlantic Alliance and NATO. Reading John O'Sullivan's columns are quite illustrative for this; Richard Lowry's occasional remarks are of additional use from time to time. That, plus hoping and praying that we've got the right cause, the right plan, and the right circumtances to, if we fight, win quickly, win cheaply in terms of our lives and theirs, and to drive a stake in the heart of the problems out there.
There's not much that a grad student can do, other than to heap scorn on the anti-war groups on grounds.
Oh yeah: I drive a nice fuel-efficient Chevrolet sedan and despise sport-utes (the modern minivan; can't see around them, they're everywhere, and the very people who should be driving Yugos are the ones who have them; moreover, the five-foot woman yapping on her cell phone, drinking a latte, praising the Golden Child, and honking the horn while driving SS Lincoln Navigator always seems to be in the wrong lane and ignoring her turn signal when crossing over on me. Pardon the vent---I about got hit by one of the above earlier in the week, and it's getting to be a regular occurrence from these types.)
