Can you use filter string to filter several OUs at same time to find locked out users of only specific

I am not a scripter so I need to see an example of how you would modify this default filter line to query several different OU in a domain including child OUs.  The reason is to find out only specific locked out users of sites for admins of that site to have notification of locked out users:

strFilter = "(&(objectCategory=person)(objectClass=user)(lockoutTime>=" & str64Bit & "))"

Is is possible to filter several different child ou's only?

I want to alert only specific admins for their specific site ou. 

Thank you,
