Would you like to receive a complementary International System Ruler (shown at Metric Pioneer dot com) just for registering as a Metric Pioneer member? No. I have no interest whatsoever. No. It is better that Americans ignore the outside world and continue learning Imperial measures because our kids will never need to know SI. Perhaps this unique ruler would be a bit useful, but I feel no motivation to do anything about my mild interest. Yes, I would love to receive one free complementary SI Ruler. I will register right now and request this unique SI Ruler. Other Done
