MissPiggy: squirrels are really too lean to waste BBQ on; this usually applies also for cats and dogs. The skunks are usually gobbled up by the plethora of owls, and I haven't brought myself around the utilize roadkill. Maybe some of the board members have some decent recipes for basic roadkill. I just hate trying to pick out the maggots.
However, before I digress, one should bake or roast squirrels in an oven. Brush some oil and seasoning and it should do the trick. BBQing is really a bovine or swine thing. I hope this helps.
