> Renaming a file on OS X requires you to single-click the file name, wait a second, and then change the file name

There's at least one other way to do it - single-click on the file, press enter, then type the new name.

and that's great because, unlike windows, it just changes the file name. Not the extension unless you actually move to the extension yourself.

All great suggestions here. Here's a few more:

- Monterey Bay Aquarium, in Monterey

- It's a good time of year to see elephant seals. There are two good places to go that I'm aware of. One is just a bit north of Hearst Castle. See http://www.elephantseal.org/. The other is Ano Nuevo State Park, http://www.parks.ca.gov/?page_id=523

- If you like wine, there are plenty of good wineries to visit in the Santa Barbara, San Luis Obispo, and Paso Robles areas, among others.
