Well, Troels makes it look easy, but I do think that is a great method. I'll give that a try, but perhaps with less wave action. Thanks for the suggestion, I had forgotten his videos even though I have followed his Coast Line thread for years.
Mark, you are right, this kind of setting seems to need a lot of trees! I have lost count of the actual trees, but I have used over 1250 feet of 28 ga wire for branches and almost 200 feet of 22 ga for trunks so far. I won't need many trees for the Ashcroft and Thompson Canyon scenes, so I figure I'll do this scene up fully and not skimp. Based on the 50 trees I placed today, I would say I need another 300+ to finish the Cisco scene.
