Louisville, Ky To San Diego, Ca, Winter Trip Advisable?? Options

[nancylouie]

We've been to Florida for the winter months (Jan-Mar) and always find fun places to explore and know our limitations about where to go and find the warmest weather during the winter months. Last winter was crazy warm everywhere so we certainly don't anticipate it'll be that way again! We are, however considering making the trek from Louisville to San Diego via a southern route that will give us some places to explore along the way. I suppose going Route 10 west is the traditional way to go...but we always like to travel those 'less traveled' avenues. We pull a 25 ft travel trailer and will have our two dogs with us. Would love to hear any experiences you've had with perhaps a similar trip. I'm also very interested in hearing comments about how safe it is to go into Mexico these days. We have our passports and might consider a trip across the border. Thanks! Nancy and Louie near Louisville, KY
