Texas in the winter?

There are nearly 500 RV Parks in the Rio Grande Valley, Prices start below $200.00 per Mo plus Electric. One nice low end park is Golden Grove Near Mission. Good free WIFI, Good size sites and near Bentsen State Park & the World Birding Center.
Also paved bike trails nearby, No Pool & few activities but several adjoining parks have many activities open to the public. The Rio Grande Valley will be the warmest area of Texas, We have not had a frost for the past 2 years.
