Lately, it feels like all of our date nights are on the rocks. Or on the rock piles at least. We've been spending a lot of time geocaching lately. And it's pretty amazing how many ways there are to turn a rock into a geocache. Dan has made a few of the real rock caches - rocks he drilled holes into to insert bison tubes into them. He bought two drill bits - a pricey diamond encrusted one ($20) and a regular mason bit ($3.50). The diamond one did not work well. The $3.50 one has been great. Go figure. A 5/8 bit works well for a half inch bison tube. My least favorites are the "needle in a haystack" caches. A rock, in a pile of rocks.
