I run pink through and once done i drain it out of the system, set all bypasses back to normal use. No need to leave the pink in the lines all winter. Come spring we go camping and we don't drink we don't even drink water at home from the tap. I know i have issues.
It is amazing there very clean and well kept it camping at the fort is like having 2 vacations you get to experience a top notch camping trip and you get to do the park as well. Get the hopper pass and you will have a blast.
