I love countering this one with... "Here's the choice.... I get to take a 3 hour ride that costs me nothing but some Clif Bars, gels, and gatorade..... or I take up golf and I'm gone with the boys for 6+ hours for the round and shell out dough for greens fees and post-round drinks...."

I've gradually built up the acceptable level of riding time, and I didn't even get my road bike till after our first kid was born! With a second one due in about a month, I'm doing whatever I can to make the wife know that cycling keeps me sane and I think she understands that. She also knows that the baby better get here by its due date or earlier, or else I'm going to have to miss the Horribly Hilly Hundreds.... hmmm....
