The Locked Gate

Down this path
There is a gate,
One that’s on
A downhill straight.
You need a key
To get past,
But most just peek
Like through a glass.
To use a key
You must decide,
If you are ready
To take the ride.
For the key
Is for trade,
But only for
Sweat, tears, blood and blade.
What is on
The other side?
A real good place
To go and hide.
