There used to be a little caravan thingy that went round the country fairs down here. Sold all sorts of exotic stuff, bison, rattlesnakes, kangaroo, ostrich. Even sold locust or ant ice lollies. Rattlesnake was decent but it was expensive, can't remember exactly but me and a mate shared at a pack, think it was about £20 for a half pound pack and that was about 10 years back ?
