Great progress this weekend! Grading (subroadbed, risers) are complete from Lizard Head all the way into Rico, and from Dolores (under Lizard Head) all the way thru (under) Rico and nearly to the return loop under the Enterprise branch. I'm using 1x3 or 1x4 risers, screwed and glued for stiffness, and 1/2" subroad bed about 4" wide in most places. The templates for 30" curves w/easements are working well - I use them to trace single pieces of subroadbed as needed, combining curves easements and straights into as few pieces as I can, which really helps to create a smooth route.

The picture here is the grade from Lizard Head descending into Rico, with the line from Dolores appraching the grade under Rico.
