LOL @ Hooch! I divorced someone who likes guns & camping & live with just the opposite now - well thats another jerry springer show.
on to the OP. coming from a female who is a tom boy my advice may be about as good as some of the men here.
besides bugs - what is it that she does not find fun?
What are your wife's interests?
if she agrees to try camping...
clothing is important. have fun shopping for clothing to help keep the bugs away, to stay warm/dry.
perhaps find a place where you can camp & go visit a nearby attraction that she may enjoy - do it as an overnight at first.
pick a place that may not be crowded with other people. something with pretty surrounding near water. If she doesn't like fishing don't take fishing gear & dont talk about it. However, if she likes photography or bike riding for example - do that. take her for a canoe ride? Its all about HER! - make it some what romantic? (this is where I lake skills)
A bug net perhaps tied to a low branch to make a nice eating area might give a relaxing mood while eating or reading a book. use a ground cloth to make a nice picnic blanket.
if not at a park like area where you dont have facilities. create a private designated private space.
food & snacks are also important. keep it simple but bring comfort food.
PS. oldgringo has a point. Acceptance. I know many couples who have never taken a vacation together & are married many many yrs. She goes to the spa & he goes camping. it is what it is. probably why they are married so many yrs! - and as long as they accept your time away & vice versa. all is good.
