Anyone out there have access to LIDAR Images

I have been reading about the accuracy of aerial LIDAR images, looks like its the next step for super accurate maps. The Granit Website lists that they have access to two data sets from the WMNF although both look like they only cover the western half. I expect that if the data is accessible it will open up locating old logging paths and potential places to visit when and if it becomes viewable to the general public. Any one out there have any idea on what is needed to read the current data sets? and has anyone successfully accessed it?

Knock yerself out: NOAA Digital Coast Data Access Viewer

Interesting viewer but it doesn't seem to have a way of loading data and when I search NH for USFS data there is none available.
