Larry,
Ringwood and flowy don't really go together (minus the white trail), but it's defintely a fun park and manageable to intermediates and above. This is the route I've been doing most of the times to incorporate MOST of the park:
Starting from Lot C, go across the road and take Duck Pond Trail
Keep right to stay on singletrack (Black Bear Trail)
From the soccer field at Ryerson take a left and follow the double track until it meets up with the Red Ringwood-Ramapo trail and climb that for a while
Left onto Cat's Nest and have a fun downhill
Left onto the fire road as you exit Cat's Nest and follow that straight to the white trail/Poison Ivy: go right and climb that to Weyble Pond
Turn around and the descend the trail you just climbed and follow the white all the way down and back up until you get to the Ringwood/Ramapo (red) trail
Descend Defiance Rd all the way back to Lot C (good time to refill water/snack if needed)
**This part I hate...Is there a better way to Link Lot C to Shepherd's Lake? Maybe Shepherd Pond Trail (never tried it)** follow the paved road all the way to Shepherd's Lake and bear right to the gravel path and right on the Race Trail (RVCC blaze)...May be hard to see but you'll see clear singletrack that climbs from that gravel path
Follow race trail until you hit Skylands Trail (blue)
Skylands to Ringwood-Ramapo again (red)
Ringwood-Ramapo will meet back up where you climbed White, keep following the Ringwood-Ramapo trail (warm puppy)
After descending from warm puppy you can continue across the road and eventually meet back up at Ryerson and follow the Black Bear and Duck Pond trail back to Lot C, or hang a right as soon as you hit the gravel fire road which will be a relatively short paved road that will take you to Lot C

This park is tough to navigate and easy to get lost/sidetracked and I had to follow some regulars there before getting the feel of the park. There are a lot more trails out there that you can hit and make a larger loop but this route seems to flow pretty nicely and make for a good workout on the bike.
