    Some primitive areas to camp. State park is nice for shade and a shower. Gas station store open 4 am to 10pm. Good, inexpensive food there, too. They have a grill and even an ice cream shop. Better tackle selection to the east a mile or so at the Mardon where there is also a restaurant, ice, etc.
