Poem about a picture

Hi guys, here is a poem I wrote and it's about a time when I was in Auckland in Rainbows End.
Title: Rainbows End
Here is the poem:
A sunny Autumn day,
there is no rain for the whole day,
it was a cool day,
me and my dad thought it's going to be awesome.
We're going to Rainbows End,
we went in Rainbows End and it looks interesting,
we got on the bumper boats,
we went on a log that's on water,
we went on a train-like thing that goes over a short mountain,
we got on a moving but fake car,
me and my dad went on a fast but fake racing car.
me and my dad had three chocolate chip cookies and a can of L&P for lunch,
we went into a maze after lunch,
we took photos of me with people in Rainbows End dressed in costumes,
I had lots of fun and it's a wonderful day.
What's your poem about and why did you choose it?
