My daughter and I did a little comparison while we were in Las Vegas, I forget the final count but we basically counted all the DSLR's we saw while walking on the strip, Canon was the obvious camera of choice with most being Rebels. Nikon obviously second but it was something like 1 to 5 and Pentax 3rd. What I think is that Canon has a lot of loyal customers who used their point & shoot digitals so when people graduate to DSLR they reflect back on their Canon P&S experience which have always been top reviewed cameras.
Also this is a tourist spot, like the posters location, so maybe the average tourist uses Canon while more serious photogs may choose Nikon. At a professional event the count may be quite different.
