Oh gosh, I hardly know where to start.
I mean, everyone knows about the KU Jayhawks basketball teams and their famous Allen Fieldhouse, but the town has also got great golfing, boating, fishing, cycling and hiking opportunities if you'd rather do more than just cheer the 'Hawks on.
9-hole Executive golf course is kept nice and green and is fun to play. No par 5s, so keep your shorter game fine-tuned by renting some clubs and spoiling a good walk.
Equipment: Clubs can be rented, but bring 'em if you got 'em.
Lots of pool tables for rent, and karaoke (shudder) on some weekends. Good place to kick back with a tall beer and relax with friends.
Bowling - a good way to pass the time with a beer and nachos.
Equipment: Rent balls and shoes if you don't travel with your own.
