I have hung sans tarp for unhindered view, and have got up in a hurry to deploy the tarp as well. Postal makes a good point about ABMs (Aerial Bowel Manouevers). The best compromise is probably pitching your tarp in porch mode. One of these days I plan to use some super six (vapour barrier) as a see through tarp for maximum view and protection from birds and rain.
