ATVOBSESSION

Mine:

"ATVs and motorcycles - living in harmony September 22 through November 4"
or
"Let's work to share the road ALL the time"

except if there is any rainfall or any tiny bit of snow then its closed to all.

"You can share the road on occasion if willing, but you can NOT share my burrito..." ?

OR PERHAPS~

"Sharring this road will be strongly advisable and highly recommended between September 2022 and November 2104, although by then it is very unlikely that use of ANY combustion engine in ANY motorized, wheeled vehicle (including any said vehicles with 1 or more wheels and a rider/driver/operator) will be allowed... subject to change without any further notice. PLAN NOW FOR YOUR GRANDCHILDREN'S FUTURE!"

It looks like some thing that Sierra Club would do and put it on a road that the Travel Management plan closed. Just to rub it in our face.
