GPS is wonderful

Without GPS I couldn't have done what I did yesterday that is certain. I had to take my colleague Tim Wilson, and our friend Tim Kitchin to the airport in San Francisco, TW at 1pm and TK at 5pm. So we headed off blind from Monterey up Highway 1 through northern California in the direction of San Francisco. GPS guiding us all the way into the airport. Superb. Without a map we'd have been stuffed as the freeways around SFO are complicated!
