[Texascavers] OT - Vacation to Mexico

[Sheryl Rieck]

George and I are planning a couple of weeks in Mexico and I would like
opinions and some 'sites to see' information from anyone who feels like
sharing.  

 

We will cross at Eagle Pass and go to Mazatlan and then down the coast to
Zihuateanejo.  After that, we will wander our way back up to Matamoros.  We
haven't been over in a long time, so I wondered if anyone had suggestions.

 

Also, does anyone have Mike Walsh's email address?  Or, give him mine,
shri...@cableone.net . 

 

Thanks.

Sheryl

Sheryl,

  If you're going down the west coast, I would highly recommend Copper 
Canyon (Barranca del Cobre).  A bit to the north is the spectacular waterfall 
Cascada de Basaseachic, over 800 feet tall.  Both of these are nominally parks, 
but when I was there you could basically do whatever you wanted, within reason 
of course.  These are fairly high alpine environments, so be ready for snow and 
cold weather in December.

Wasn¹t the ³bat mobile² turbine powered? If Batman had a turbine back in the
60¹s.it seems like the vigilante police industry would have created a
consumer version by now. Seriously, they could create super-heroesque
consumer vehicles and provide jobs and real job training for ex-themed
psychotic villians that were seriously altered in radiation related
accidents...and our streets would be safer as a result.
