[GRASS-user] getting LiDAR data into GRASS

Hi,
I'm new to GRASS. I am using 7.0.5 on Windows 7. I have LiDAR data in 
.las format that I want to reclassify in GRASS. I read, I think on 
Stackoverflow.com that one can reclassify in GRASS, thus my desire for 
this task. I looked up help for using GRASS with LiDAR and found the 
wiki, but it seems to skip steps. Does the LiDAR data need to be in one 
of the GRASS locations, like "spearfish60_grass7" for the Spearfish 
practice data? Or can the data sit in a folder outside the GRASS 
directory and be imported from there anyway? When I look at the 
structure of that directory, I don't know where to put the .las files.

Tangential to this, I don't know what command to use on the console for 
importing or making a connection to the .las files. This is what I tried:

(Tue Dec 06 12:36:10 2016)
v.in.lidar -p 
input=C:/Users/Admin/Documents/grassdata/okmulgee/f35096E1_NEA_PrjAdd.las
(Tue Dec 06 12:41:39 2016) Command finished (5 min 29 sec)

It says that the command finished, but I don't know where to view the 
layer. I tried:

(Tue Dec 06 12:42:46 2016)
g.list vect
country_boundaries
mysites
point

Doesn't seem to show anything related to the LiDAR that I tried to import.

Can someone please tell me 1) where to put the .las files, 2) the 
correct way to format the input for the v.in.lidar command and 3) how to 
verify that the data are loaded.

Sincerely,
John Polo
