Westover Park
If you're tired of studying for those mid-terms and are looking for something fun to do during the spring semester in Harrisonburng then you should go to Westover Park and play some frisbee-golf or "frolf." The course at Westover Park has 18 "holes" (metal baskets raised about 3 feet off the ground), and is quite challenging with a par of 3 for each "hole." Each "hole" is surrounded by beautiful scenery, with a LOT of trees. For anyone who's played frissbee-golf before you know that trees make for a rather difficult course; making par itself is pretty difficult on some of these "holes." Whether you know how to play or not "frolf" is fun for a couple people or even a small group. Just bring yourself and a frisbee and enjoy the game.
Or if "frolf" doesn't sound like something for you, then head over to Westover Park in the 'burg to play some pickup basketball on Tuesday and Thursday nights. WARNING: these guys are really good - a lot of the guys that come to play are on a divsion 1 level skill, so you better bring your best game. If you're thinking about playing basketball for EMU, then playing at Westover on Tuesday and Thursday nights will be a good place for you to practice in a more competitive environment. It's a lot like a playing an intense pickup game in the Bronx or Brooklyn.
Finally, Westover also has a huge community pool if you like to go swimming as it starts to get warm and finals come around. Or you can also go workout at Westover, or play pool or ping-pong. Whatever works for you; it's just important to find places off campus in the 'burg every now and then to shake off the weekly stress.
