More on the mosquito issue.  Zapping mosquitos can be a satsifying adventure for those of us with a killer instinct.  But I think its probably more satisfying to keep the little buggers out of the van.  The best way I've seen is with an electronic mosquito repeller.  They can be found at the following website.  http://www.harborfreight.com/  Once there, do a search on "mosquito."  The individual repellers are also sold on eBay.  Do a search on "mosquito repeller"  and you will have a choice of Sunbeam and Coleman models.
