Information about Willow Creek Park :
The problem with Willow Creek address is if you come from Verlin Rd (hwy 43) it is Guns St but from Allouez Ave (off from GV and 172) it is Guns Rd. We deal with this all of the time. Mapquest takes you to same place but if you are just driving and looking for Guns St. from 172 it will be road. The Village lists it as street but then in their description of the park they say it is just off from Guns Rd.
