Any (public lands) ground blind hunters?

[Nilehunter]

   I have been thinking about picking up one and trying it out.  I was just wandering if any one has any experiences using ground blinds and which one.  I am curious if it helps with masking scent or dose it present problems I haven't thought about.

Thanks for any input.

i use one from time to time and has worked very well in the late season. on those days when it pouring down rain in the primos blind im nice and dry! its just hard to know where to set it up if your not hunting the same spot over and over again so you know where the animals are gonna come through at.
