I’m of the opinion that the extreme national parks closure it meant to impact the red states and red areas. The 40%+ die hard obama voters living in the blue areas don’t give a crap about the impact to people living in and deriving their incomes from proximity to national parks.
And those die hard blue suck voters who work for the park service are going to get back pay anyway so their discomfort is minimized.
I’m quite sure my HUMMER would be able to successfully navigate any cone obstructions, or topple them all for that matter.
