Lyn - Della doesn't seem to like it at all. She starts to fry at about 85degs and shatters quickly in 90+. But, again, look at the altitude differences. Even at your .. what.. 3000ft? is a big difference than 6000ft. Every 1000ft the sun is 6% more intense, so the sun is about 36% more intense here than it would be like in Zuzu's yard or even Debra (she sits at probably 500ft.. when I was there, I was testing the altitude to see if I can breathe OK there.. the air's too thick!!). And I rarely have a pollution problem in my area (unlike the foothills or downtown Denver), so, when the sun's out, the sun's OUT. You can get a nasty burn in about 20 minutes w/o protection.
