I spent so much time looking for something like this.. thanks!

I was wondering if there is any way to make this code run faster? I'm guessing no, as the longest time component of the code seems to be retrieving the information from Google. Thought I'd ask though, as I have a list of 40,000 zip code pairs to calculate. At just over a second per pair, this takes a long time.

Maybe it's time for me to upgrade my internet service!
