Colorado leaves from 2009

Fall has got to be one of the most beautiful times of the year.  I live in Arizona and we don't really get to see the change in leaves from summer to fall.  Most of our trees lose their leaves in February.  But most states around the country you can experience fall foliage at its finest.  And best of all, it's free.  You  have to check out this site for the top 10 spots.  And check out this link for locations from coast to coast.  Enjoy the free beauty of our country.
