MTA Firecracker Block Party. Our next block party will be on October 20th during Midlothian's Fall Festival from 1pm to 3pm. You don't have to be a tennis player to attend. So mark your calendars and bring the whole family for some fun and prizes! Our last block party was cancelled due to rain. Pictured are the festivities from the 2006 MTA Firecracker Block Party. Thanks to the help of the members of MHS Tennis Team and the USTA (United States Tennis Association) the Firecracker Block Party was a big success. Thanks again to everyone who came by.
