They still have some Kulana bikes, just not the Moon Dog that seems to be a nice bike to convert.
I found a cached link to the Moon Dog bike at wally world before they removed it from their search:

Walmart.com : 26" Men's Kulana Moon Dog Cruiser : Bikes, Scooters & Skates

You notice it says: Not Sold Online/Not Sold in Stores

I just hope they don't get rid of the red Schwinn that I plan on coverting also.
