3. Rewards or ...? Mystery Cache

It must be the anniversary of something he doesn't like to talk about because the Evil Puppeteer has been locked in his room all day listening to John Denver - I didn't even know he had his CD,

He came out only to hand me a box full of a certain kind of treasure with an attached riddle and coordinates.

As he walked away he mumbled "If they want it though, the dirty little gremlins have to work for it!!".

So... rewards or... nothing? Your choice.

He moved Bournemouth in 2011
Bournemouth nearly moved him in '16
There's blue skies on the way to heaven
He's travelled west from where he'd been

Between both of these points at the T
Take a northerly stroll within sight
Find an ornate red utility
And then make a turn to the right

If it was dark now you would struggle
Be it not for my lucky thirteen
Be very wary of a muggle
And make sure that you are not seen

I've posted two guards for this treasure
I insist that you now sit between
Take a photo for stealth or leisure
But exclude if metallic and green
