Sorry, had some misinformation in my previous email. Expect the cab from Dongzhimen to the field to cost
40-50 rmb.
**DETAILED DRIVING DIRECTIONS**
If you're going north on Fifth Ring Road, you'll want to take Exit 47, i.e. Bei Hu Qu Lu (北湖渠路), specifically 47A (i.e. don't turn right when you get off; 47A is straight ahead).
Exit 47A will loop you around the top of the overpass. (You'll see "The Maccaline: Global Furnishing Design and Exhibition Center.") You'll want to take a LEFT at the FIRST STOPLIGHT after the overpass. This left turn takes you directly to a security gate; the guard should know there's a Frisbee event. Go down that narrow road ~1 km, i.e. get off when you see the next security gate.
