What to do with a train...

Ok, the Pfalzgräfin Dorothea Sabina von Neuburg dress from JA's PoF has a train. And I like it. I've cut my skirt with a train but the reality is that I'll be wearing this outdoors over dirt, rocks, twigs, etc. 

I've see the Holbein sketch of the Tudor dress kirtled up in the back but I've never seen anything showing later period dresses pinned up. Is there such an example out there? Or any such evidence as to what late period ladies did with their trains out of doors? I really don't want to cut the skirt straight but I will if kirtling was just not done around 1600.
