[pct-l] off topic: gps usage... in France/Spain

[saskia.home at xs4all.nl (Saskia)]

Dear friends,

I am so sorry to post something off topic, but I am hoping that one of 
you out there knows more about this. I am planning to go hike in the 
Pyrenees, on the border of France and Spain. We are debating whether we 
should take a GPS or not. Have you found it useful in general, has any 
of you had any experience in the Pyrenees with a GPS, do modern GPSes 
always recognise the French 'Lambert' grids, what grids does Spain use?

Thanks for tolerating the intrusion.
Best wishes,
Saskia
