The Pottruck Center is 19,000 square feet of everything your physically-fit heart desires: free weights, elliptical machines, treadmills and exercise bikes, dance and martial arts studios, an Olympic-size pool, basketball courts, a Pilates studio, a climbing wall, you name it.

But there is one piece of equipment that seems to always be in short supply: lockers. If you have had trouble securing a Pottruck locker in the past, now is the time to act.

Tomorrow (July 23) is the deadline for Penn Recreation members to renew their Pottruck or Hutchinson Gym locker rentals for the 2010-2011 academic year, or to enter the locker lottery and win a chance to rent a locker.

To enter the lottery, members must visit the Pottruck Center in person, fill out a form, and provide a VISA or MasterCard number to charge should he or she win a locker. At that time, members must also renew their Recreation membership for the year that begins Sept. 1.

The lottery selection is set for Monday, Aug. 9. Winners will be posted on the Penn Recreation website on that date.

A full-length Pottruck locker costs $150 for the school year; a half-length locker in the locker room costs $125; a half-length locker on floors 1-4 costs $75; a quarter length locker costs for $50.

In addition, the Pottruck Center is now offering full-time University employees who pay for their membership via payroll deduction the option of renewing their memberships online. The deadline for renewing for the 2010-2011 school year is Tuesday, Aug. 31.
