Do you know of any sites that I could find some recreational shapefiles?
An example would be shapefiles of golf courses, ski resorts, or maybe baseball fields in the United States?

I would suggest checking the other other questions that have the POI tag for a more comprehensive list, but a couple that come to mind right away are:

But Open Street Map is likely to be more up-to-date.
If your in the UK, the Ordnance Survey has a vast collection of data now available in public domain.
The "OS Vector-map Product" has lot's of things in from amenities to leisure centres, churches and a whole raft of other things.
There's many other map products too such as "Strategi Map" that include usefull data sets, all is available to download as Shapefiles, and they'll even send you the larger ones out on DVD's free if you request it.
