Every year in the area where I live there is what's called a "Tulip Festival" where hundreds of thousands of people come to see the tulips. There are several fields scattered throughout the valley with loads of events accompanying the flowers. When I was younger I never understood why people would travel so far to see the flowers, but now I appreciate the vibrant colors and greenness of my home valley.
Here are a few pictures of what the fields look like. There are many different colors of flowers and countless acres of fields to walk through. The only pitfall is this event takes place in April in Washington, so there's most likely going to be rain, if not, the fields are still extremely muddy.
