Dang man, sorry to hear about your deer troubles... I have been thru that so I know. Good idea about saving the urine, that will def help. Couple things... I notice your spots are pretty out in the open, like meadows and what not. Those tend to be places deer go to feed. Might be a good idea to choose more difficult spots to get to. When guerilla growing I always choose a spot that is as difficult as possible for me to get to. This will help but not eliminate the chance of animal or human finding them. Also what you may want to do now since they are already in the ground is run some fishing line around your plants. Use the existing vegitation as support and make a perimiter around them. To be safe I circle around 3 or 4 times about 1 foot apart from ground level up. Same concept as chicken wire but much easier to lug in and good thing is it's really camo. Hope this helps and good luck dude.
