Can you join a local club with access to one of those many tracks? Beg or plead with one of those college coaches to get a peak at their track once a week?
NO? OK, run on roads with less traffic. Try repeats of 3 - 4 phonepoles (300 meters), 8 - 10 repeats. Maybe two minutes between. Go out for a 6 - 7 mile run and stick these intervals into that run. MIx up the number of repeats and number of phonepoles at will. In the heat of the season, you can do this workout 3 times a week.
You'll run 10 minutes warm up before the first interval. Start slow and get to about 6 minute mile pace before the first interval. And, ease into the intervals, take it easy on the first repeat.
I used this type of workout to build to a 1500 indoor PR in a cold-ass Massachusetts winter during the 6 week semester break. Triple layers over the unit to keep it from freezing off.
And, I have a question. When you are running the 800 on pure hate, are you remembering to run relaxed???
