Sharon meadow boot was a resounding success this afternoon. Between the nicely flat grass without ankle traps, the healthy supply of sunlight, and the adjacent pickup games for folks who want to run around and pwn some noobs, it has all the elements of a better location. So we'll plan on playing there from now on. 

It's been described as half-court ultimate or hoopless goaltimate.

A field about 30 yards long has one Nalgene at either end and a middle line. Teams of 3 or 4 attempt to knock the Nalgene over by either throwing the disc at it or using the disc in hand to knock it over. Once a team "clears" the disc across the mid-line they can score on either end.
