Hi Rich, You are correct about GRID being a raster format in ESRI world. But from your description, I believe what you have is a coverage, which is ESRI vector format for ArcINFO (shapefile beeing another vector format).
LiDAR data is obtained as XYZ point cloud. That's why you probably have vector data. Further processing is needed to transform it to a raster format.
