A little late, but this one makes me happy every year:
Walking home from work on Friday with the dog, and we saw our first gophers. Big, fat, lazy gophers (apparently the winter wasn't as bad as I thought, or they a great job stockpiling food last year!), just hanging out beside their holes. Seeing them always gets the mutt's craziness going - but I only let him get close, not enough to actually catch them. (As if he could anyway! They're usually super quick...even the fat ones)
