Anyone know what the trails are like in Rockburn Park in Maryland?

I may have a chance to go riding at Rockburn park in Howard County, MD, and was wondering what the trails are like - wide dirt trails, rocky, sandy, hilly, flat? And is it a busy park with lots of hikers, dog walkers, families, cyclists, or mostly horses?

thanks!

Read the website. It looks like it is primarily a biking trail
