The Exchange Rate Droppeth

Last year when I was in the United Kingdom, I arrived to an exchange rate of about $1.70 to £1.00, and it slowly crept up to about $1.80 while I was there. For a lot of this year, it's been about $1.90 to £1.00. I checked it this morning and it appears that things are calming down, though who knows if it will last.
