You do understand that when you resort to name calling when you are confronted with facts, if that is the best you have to offer, you have already lost the debate.
Further you do realize that in addition to docks and repair facilities that there is a Coast Guard auxiliary at Lake Mead? Also, as for “other needful buildings” how about Hover Dam? I would certainly consider Hover Dam a needful (power production for one) building.
Remember the first rule of debating. The one to start calling names has lost the debate.
I didn’t resort to any name calling. None. Why are you resorting to lying?
Wow, I’ve been to Hoover Dam and I didn’t see the cattle grazing on it. Or near it. I didn’t see them in the marina, either? Maybe they were all using the “needful facilities” at the Visitors Center.
