Just kidding - Where do you want to live? That might get some agents from that specific area to come and reply.
Otherwise, go to Realtor.com; Craigslist, and many other sites to look for land.
Your county / city planning department can also show you where vacant lots are but then you have to go find the owners - not too efficient.
Call your agent!
