Wow! Picnic areas usually have built-in grills, I didn't know that!
Yes I live next to a park, it is a good idea as it can help to prevent fires.
I guess grilling is nothing new, as it has existed in the Americas since before the Europeans got here.
I guess the Native Americans tried to eat raw meat and thought "we could do better"!
Too bad the Europeans thought Native Americans were "backwards" and instead spread (even if unknowingly) their diseases and their gunfire.

Native Americans in the United States
Native Americans, also known as American Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States, except Hawaii and territories of the United States. More than 570 federally recognized tribes live within the US, about half of which are associated with Indian reservations.

Michael was just very kind to, you know, let us finish equally. I guess I pointed a little bit in front, but, you know, what can we say?" Schumacher
