Rollercoaster progress.

I was building my new rollercoaster,that will end on bedrock i found.
Lets move on.
I had to finish my old one.
So,lets do this.
I mine,makes torches...and look!My old friend is here!That means...iron!

But notch says 'never dig straight up'

What if lava is above?Better not mine it.

Lets continue.

I was going down when...GOOOOOOLD!

Finally found in ages!

Okay,lets continue.But better mine this.

Okay...later...Iron!

But better skip this...and...REDSTONE!

I think this is the BEST WORLD EVER!!!
