There's trails in them thar hills

The question is how do I get to them? I drove around today trying to find a way out to the edge of town. I board my horse in urban sprawl that is criss-crossed with gravel shoulders they call bridle-paths. It's better than the other side of the 95 freeway which has horse zoned properties interspersed with tract homes and sidewalks. I started mapping out mileage, so when I get out of this arena, I'll have some idea of distances for conditioning rides. The 215 Beltway girdles our fair city in an attempt to contain us, but I'm sure there's a way to cross and get out to those hills. The obvious solution would be to trailer out to where the good trails are located, of course, but, oh wait, I don't have a trailer. Ann Road intersection looks promising. There's a traffic light there and it's the narrowest part of the beltway. I have an image of that 14 year old boy indelibly impressed on my mind. He and some friends tried to run across the 215 at night; he didn't make it. I happened to drive past his body just before the EMTs covered him. My heart goes out to his family. Needless to say, I'm looking for the safest way to cross. There's also a pedestrian bridge that specifically allows horses at another location. We'll see. I told another boarder that I had a goal of doing an LD in October. Of course, it depends on how we're doing. She said,' that's ambitious'; she doesn't know me very well, clearly. I'll have to beg, borrow or rent a trailer.
