I'll summarize our experience. This is our third winter in the RGV.
Entertainment: Same old same old.
Weather: In 3 months last year went thru 3 tanks of propane, this year in 2 months went thru 6 tanks. Arrive Jan 2 and on the 3rd low was 27, on the 4th was 28. Last year if I wore long pants it was Sunday and we went to church, this year wore shorts ONLY 4 times. No winter tan.
Went to Progresso once and one Mexico tour, felt safe both times. Had a friend go to Matomosso (sp) and said never again.
All in all it was great: NO SNOW!!!!
We are now on the road thru AZ, CA, NV, & UT on the way back to WI and already looking forward to the RGV next winter.
