Dear Editor,

Brockingham is run by people who are more interested in tourists than its residents. The problem is that the people running the government refuse to accept new ideas. By banning(禁止) all fast-food restaurants and discount stores, they take away all the places kids can afford to shop.

These people forget that when they were young, they could go to the South Street Soda Fountain and get an ice-cream soda for 25 cents. Today you can’t find an ice-cream soda anywhere in Brockingham for less than $2! Where can kids go for a snack?

There is not a single restaurant in Brockingham where a family of four can eat dinner for less than $100. Add a 15% tip and sales tax and you have spent nearly $125 to eat a meal you could prepare at home for about $12. Have you noticed that Brockingham families never dine in Brockingham?

Fast-food restaurants are also a good place for school kids to get an after-school job. Fast-food restaurants are busiest during the early supper hours when students are able to work, whereas the fancy food restaurants cater to late-night diners. Working in one of these establishments requires working shifts that are too late for most students.

The City Council claims that local merchants, rather than national chains, should benefit from the tourist business. I agree that it is important to support local businesses, but I think the fast-food restaurants would encourage more people to shop in Brockingham.

Another thing that disturbs me is that we must travel 25 miles to the nearest discount store. If I need a tire for my bike, I have a choice of buying one at Surf and Peddle Sport Shop for $15 or driving to Parkersburg Discount Center where I can buy the same kind of tire for $9. Again, I think the ban on all food chains and discount houses is counterproductive for our city.
