Beautiful! I do like that area. I spent some time near Grand Forks, but on the WA side - with weekly or semi-weekly forays across the border.
Are the Sylix one of the Salish tribes? The sounds are so similar. I love how some of the local trade languages are being taught again.
The Okanagan is amazingly awesome, id recomend it to anyone ahaha, just in the summertime only. So lively here in Kelowna...
I think they are salish... I am not sure though. They do teach the language here too!
That's awesome on the language part.
I loved the winter up that direction too. :)
