Poor pups. I take it, they are staying at home.;-)
Sounds like fun, don't forget to turn over every 20 minutes.. and use sun block :-)
It will be fun, Norm. Puerto Vallarta, MX is one of my favorite places on the planet; and I've been around it a time or two already.
Highly recommended if one wants to escape sub-zero temps for a while. Cheap. Clean. And for some reason, no bugs! :)
