My son Eric who lives in Albuquerque, NM sent me this link showing a time-lapse of this years hot air balloon fiesta. It is well worth a trip to see it in person if you have a chance. Every year early in October ballonists from all over the world congregate for a flying party. If you can spare five minutes or so, have a look here:

I have experienced it several times and it never ceases to amaze.
