If you haven't been to Las Vegas, imagine that each hotel property is the size of a mall. It can take hours to walk the strip and it's very easy to underestimate just how long it will take since everything looks close together.
We did a little shopping as Canadians love to do ("OMG Target!! Kohl's!! JCP!!") and while on the way back to the timeshare we stayed at with our friends (itself surrounded by empty lots), I noticed these giant pillars that reminded me a bit of the poem "Ozymandias"
The two giant legs, in this case, belong to the Skyvue Las Vegas Super Wheel which was supposed to open in 2012. Signs around the lot advertised that the land was for sale. It joins the "Voyager" as an unbuilt ferris wheel - and in case you're wondering one ferris wheel did manage to get built, the "High Roller".
