You can set up an automatic search where the instant ANY home is listed by ANY brokerage YOU get the email of ALL the info; price, address, pictures, virtual tours etc etc...
Hope that makes it a little easier for you Ken!
The link below shows the 122 single family homes in Carlisle that are currently listed on Trulia. Perhaps you can use the map to locate homes close to where the car shows are held.
I hope this helps you.
