holding tanks and freezing

[fwernlein]

I use the red RV antifreeze..costs more, but IMO easier to carry and
add than rock salt.

I posted some general winter RV info on Wanderlodge FC awhile back
on what has worked for me...see files.

Have a great visit. Should be no crowds...at times i even have
found room for street parking the BB along the Mall on weekends
early morning.
