Are you looking for an educational family activity before school starts back up?
Living Social has a great deal today:
For $13, you will get admission for two adults and two children to the Planetarium at The University of Texas at Arlington plus two servings of astronaut ice cream! (Vouchers must be redeemed by November 4, 2011.)
This is a great indoor activity for your family!
*From what I understand, the voucher is for 4 admissions, which can be redeemed all at once or over several trips.
