I am sure as a fair minded club, as yours most likely is, your club wouldn’t try to prevent folks(tax paying... you know...the ones paying for the park Rangers and such) from using the park or willfully maintain an erroneous position that one must belong to the club to fly there if it were actually a park... Your club may very well have met all prerequisites to acquire the sole use of public property and would be paying for a substantial lease. If so, your club is contributing to the actual costs involved but many other clubs only pay a token fee for a non-exclusive use lease, which is common.

It would be hard to fathom ( detect a note of sarcasm here) a club that would try to take advantage of Joe Q. Public’s ignorance and try to dupe him into believing he can only use a park flying field under the clubs conditions.
