I remember about 5 years ago I happened to go to Walmart with my youngest son on the Saturday closest to Halloween. After we walked in we realized that they were having in-store trick or treating if you had a mask on. We happened to have son's costume in the car from the Halloween parade as his school the day prior so we went back to the car and he put it on and then we went back into the store we went for some bonus candy.
Hey, I just looked and found that the Lehigh Valley Mall is also doing a safe Halloween trick or treat event:
Lehigh Valley Mall -"Friday, October 31, 2008
This year's Safe Trick or Treat takes place from 6-8pm, and all stores participating will be marked with Lehigh Valley Mall & B104 balloons. The Lehigh Valley Mall Teen Board members will be handing out Halloween goodie bags for kids to collect their ghoulish treats, so be sure to look for a Teen Board representative at each main entrance into the mall beginning at 6pm."
