Krishna.Com has a great directory, http://directory.krishna.com, for all the temples and home programs in the USA and the rest of the world.
If you are visiting another city that does not have a temple you can use this great resource. It also helpful to find multiple programs happening in the same town.
If you are having a semi regular Krishna Conscious home programs at your house and would like to invite others then submit your entry with references.
The two references can be from your nearest temple, or a GBC member. Hare Krishna
Your humble servant,
Nityananda Chandra Das
