At the east end of The Fremont Street Experience, 4th Street is walled in with fences and concrete barriers, in preparation for the Las Vegas Grand Prix this weekend. People driving on 4th Street can get a feel for the experience of driving on the race course, as the road is still open to traffic, though it is walled in and has racing related ads on the crossovers.
The Fremont Street Experience Light And Sound Show (at least the one I saw) was all Grand Prix related. It was done well, and I actually liked it for the content and presentation, rather than just the oddity factor.
In another post later today I will display some of the light and sound show. By the way, the crowd on Fremont Street struck me as unusually crowded for a Tuesday night.
