I have found 13 different cache types over my geocaching career. My best in one day is the 11 icons in 11 hours at the Geolympics (22-Jul-2012). I'm attaching the screenshots from my stats that show this.
A nice walk on to this one and what a great surprise to find those giant trees. The cache was a quick find. As I was walking off I spotted a muntjac deer - it had seen me first and was bouncing off through the woods.
