Tarping it is always a good idea, other than the condensation that builds inside. Fires are restricted in most areas I have seen, but that was before the last hard rains we have had.
You mentioned going to the winston in another thread?? There are campsites around the area, but they fill up fast from what I have seen in past years. Especially those anywhere near a water source.
The weather is predicted to be mild for the next 10 days at least, so you should be okay with the cold, but there is a potential for rain. Tuck camp back in the trees might help insulate form the rain and wind.
I have not tent camped in so long, I would be in the same boat as you. Wonder how I ever made it before the trailer........
