I took my buck this year from the ground. ASAT Leafy Cammo! I even have 2 fake oak leaf branches attached to my bow - works well even in a tree stand.
Looking back on my hunts - some of my most memorable hunts have been on the ground. Allways the more physical and mentally taxing ("can - not - move - any - muscle" said in my best "James Kirk" voice)
Want to try a tough shot - try getting a shot off from your butt. Old knees do not like being in a crouch for hours and movement is a no-no. Finally bought a tripod swivel blind chair - works well.
