To boost ratings for the shows, sometimes producers/writers have Crossovers in one episode. (ie. Some of the cast of one show "visits" the other).
In 2005/06 Season (sorry for the spoiler!), Mac (CSI: New York) will help Horatio (CSI: Miami) try and solve a case. Horatio will also visit New York in the sequential episode.
The launches for Miami and New York also had cast "visits" to launch the new series.
Now if you had your way, who would you have visiting where?
To simplify things (and make up for that confusing poll question), we'll just leave it as "New York visits Las Vegas" instead of naming actual characters.
If you'd like specific characters to interact, you can post them in here instead

... the poll box is only so big
Can't wait to see what you all think!
