More business owners should open up their lots to bus and rail riders. For instance, the Westgate movie theater lot is practically empty during the week. Offer some kind of parking sticker so people know the rules (Monday-Friday, in a certain area/certain times) or however you want to set it up.
If you allow people to park near your business, they will shop at your business! It's super simple. People need to grocery shop, etc. and if they can park right by one, they will shop there on their way to/from work.
