My recommendation would be a little different...
<cfset x = randrange(1,query.recordcount) />
<!--- display the add or whatever --->
<cfoutput query="query" startrow="#x#" maxrows="1">
... do your thing ...
</cfoutput>
The problem with converting to an array is that it can be a fair amount
of overhead (query to array-of-structs is what I'm envisioning here)
when the query itself actually comes with features that make it really
easy to use natively as well as being very mechanically efficient.
