I think it would be great to have a plastic storage bin for year around use of charcoal.  It would need to come loaded in charcoal and then refill with bags of Kingsford. It should come with a scoop and a portable bucket so you can take enough along for a one time use ... at say the park, river or camping.  It should prominently display the Kingsford Name, logo, colors, so your neighbors can see it.
