How to select rows for a specific date, ignoring time in SQL Server 2005 or earlier

Given a table with a datetime column, how do I query for rows where the date matches the value I specify but ignores the time portion?

For example, select * from sales where salesDate = '11/11/2010'

For this query we don't care about the time. Other queries require the time component so we can't store only the date component.

Thanks!
