Ringwood has a few small-mid sized drops. Someone already mentioned the drop at the top of Warm Puppy, probably 4-5 feet but really tough to find unless you know where to look. There's also a smaller 3ish footer further down Warm Puppy that keeps getting blocked off by people. The trail makes a hard left turn, but if you go straight there's a little drop to flat that essentially cuts the turn. People that know the trail probably know what I'm talking about.
There are also a few little really fun rock kickers/drops on 6 Bridges trail in Ringwood. It's nice because they start out relatively small and get bigger. You can hit them all with decent speed and they all have go-arounds, really well planned as part of the trail. The last one is probably a 4-footer to flat, really fun but watch your landing.
Last time I rode 6 Bridges was probably 3 years ago though, so stuff might have changed.
I think the best way to get comfortable with drops is to ride properly built drops with properly built landings. Ride with someone that knows the terrain and follow their speed. Spend a day at MCBP, there's all kinds of progression there from little drops you could roll to 20+ footers.
