Is everyone pregnant?

This is what I've been seeing A LOT of around our military base. I'm not kidding! Everywhere I go, I see an average of 5 pregnant women, and this is a small base. Frankly, it's a little scary. There are some possible explanations for what appears to be quite a phenomenon. Either there are a tremendous number of very passionate people stationed here, a very low supply of birth control available or there's something in the water. For my own personal sake, I'm drinking only bottled water while we're stationed in this location. One can never be too cautious!
