DS Rule Clarifications

Owen Glover and I were playing an attack/defence DS2 game on the weekend
and found a few things we would like clarified:

Woods and GEV/Grav Vehicles:
GEV and Grav vehicles are prohibited from entering woods...not even the
edges.	Surely	if a tracked vehicle can go through then a Grav vehicle
can
glide through the same path, even a bit faster becasue its a meter or 2
above the ground and avoiding logs etc ?  In the scenario, all the
defending forces set up hidden and dug in...Would it be a scenario
spefici
rule to have tank scrapes in the tree line ?  Can these vehicles
manouvre
into the tree line but not into the guts of the forest ?

Hidden Units:
According to the rules, a hidden unit is revealed the first time it is
activated or an opposing player's unit has LOS to it.  Again, the
defenders
were dug in/hidden etc but on the first activation of the first turn a
single vehicle topped a hill and just about everything was revealed ! 
This
seems a bit unrealistic given that the defenders were in prepared
positions.  We decided that for the rest of the game, hidden units were
revealed if they moved or fired (and so could call in Arty on
preregistered
targets without revealing themselves) or if a unit came within LOS AND
6"
of the unit in cover.	This assumed the units had everything shutdown,
cam
and thermal nets in place etc.	If the hidden unit wished to move or
fire,
it had to flash up its systems.  If it flashed up it could then either
fire
OR conduct a 1/2 move.

CC and Follow Ups:
The follow up after successful CC move was used heaps.	Is there any
limit
to how many follow ups a unit can do ?	We had a Power Armour platoon
infiltrate an urban area (where the HQ troop and a BR Grav Vehicle was)
and
move into CC with a dismounted Observer.  He retired form the combat
(suprisingly).	The PA followed up and CCed the HQ guys.  They fell
back. 
The PA followed up and CCed the Grav Vehicle, etc.  Can they really keep
going and going as long as they win and pass the CONF check for the
follow
up move ?  It seemed like they would cross the whole board in 1
activation!

Does anyone have any ideas ?

PS Can infantry ride Tanks ? Couldn't find any references to it.
