[Rockhounds] Garnet & Kyanite

[Lanny]

Don was dreamy eyed when he wrote that; he's probably fully awake today.

The weather just changed to rainy with forecasts of snow in the 
mountains. Funny thing about that forecast, a forecast of rain with 
snow in the mountains didn't exist until the weather changed (must be a 
weather postcaste).

If Don still wants to go, he better be sure one of his professors has a 
really good 4-wheel drive, it might be very useful. I'm going to 
chicken out and not ask to tag along.

Regards,

Lanny (stuck indoors until spring, or later)
