I am not receiving any compensation for this thing, I am just hoping to finally finish the river sets I want to get my terrain where I want it. This is a visual hobby, and I am just as guilty as others of lackluster performance in the area of terrain/battlefield management. These things make some good looking linear obstacles, as well as swamps and lakes. I recently picked up the 1" roads, and plan on getting some more from the Kickstarter.
Closer look at one of the caps.
If you are on the fence about this, give the kickstarter or Pete's blog a look. Wizard Kraft is even offering free shipping, which alone is worth a bundle.
