Narrative:

Departed iah on tower to tower clearance. Weather was VMC. Vector was given from houston departure. Transferred to hooks tower. Told to enter left traffic for 17 right runway. At this time I did not have the field in site and had not entered the class 'D' airspace. When the field was sited I was in a better position for right traffic. Asked tower for right traffic before entering. Instructions were given for right traffic. Then cleared to land. After exiting the runway. Instructed to contact ground. Parallel runway is very close to each other. The left runway did not intersect the taxiway being used. Markings are obstructed by overgrown grass. While taxiing contacted ground. Told that I had crossed an active runway. Very close proximity of two runways and poor markings make this intersection very hard to see.
