We looked at several locations including Northfield where Bass Pro Shops is on I70.
The problem was that the Malls wanted to charge us to use the parking lot and some of the requirements to get a permit from the various cities were impossible to comply with.
Southlands was very gracious and allowed us to use their lot for free. Also, Aurora made it very easy to get a permit.
I guess it is a sign of the times that the Malls and cities are looking to make a buck everywhere they can.
