The third annual haunted house and trunk or treat will be Friday at the former Lampasas Wal-Mart building at Santa Fe Square.

A costume contest kicks off events at 5:30 p.m., and a haunted house will be open from 6-9 p.m.

Tickets are 50 cents each. The haunted house is four tickets, and a bouncy house is one ticket. Proceeds benefit Lampasas Mission.
