A few friends of mine invited me to an airsoft game in a few weeks. However I kinda doupt about the field.
Is their any kind of good sense rules or clear regulations that would tell me that this field is "Concreate-solid-legal-that-won't-get-us-stormed-by-the-SWAT-the-moment-we-set-a-foot-in"?
This might have been answered before, but if it was I was not able to find it.
Thank you for your time.
