Those estimates seem off, at least based off of personal driving distance of that area and the knowledge of the roads and freeways 'round here. But hey, I don't exactly pay attention to distance as the crow flies when driving - that doesn't work well in this area. :)

I can tell you that Chino Hills is off of the 91 freeway, well south-southwest of the fire zone, which is along the 210 freeway, and that it is /not/ in visual range, as the Grand Prix fire cannot be seen at all anywhere west of Rancho Cucamonga at this point.

Correction - I typoed. Chino Hills is off the 71, not the 91. 91's further south. :)

I drive it too, to my friends who live in Chino Hills, Claremont, Fontana, Rancho Cucamonga, Calimesa, Highland, Yucaipa....

Chino Hills is more off the 57/60/71....not the 91. You can take the 91 to the 71 to get to CH....but the long way.
