Last time I was in Vegas I was on my way up to the top of the stratosphere and got up to the top then pussied out...plus they wanted $18.00 for a ride!
Would be a great investment. With 100,000 visitors a year (almost 275 a day), that would be a whopping $1,800,000 minus the financing, maintenance & staff costs.
Vegas wasn't build to entertain, Vegas wants your money...
