Cory & I were talking on the ride to Vancouver and a thought occurred to me: will the neverending stream of immigrants into the US push us into accepting the metric system (finally)? Millions of these New Americans were raised on the more logical metric system and have to master inches, pounds, and gallons along with American slang, HOV lanes, shopping malls, and the in's & out's of the electoral college.
Try teaching a child to add fractions of inches. That's the homework I really hated.
