ground blinds are nice, you can get one fer $50 that pops open in minutes and closes down even faster.
ya wont get the mornin dew on ya and it is good cover you can move around a bit
tree climbers are nice, big guys usually dont like em, but young kid with his dad and a safety harness is will be ideal fer ya as well, dad will be checkin on ya sooner or later.
unless you have a ghillie suit and know how ta use it, sittin next to a tree aint much fer cover, but can be better than nothing
