i guess this answers several of my questions - not sure how i missed that
i guess if you don' have the prusik and carabiner you adjust the tarp placement and tension using the taut line hitch? and i following that right?
but my other questions - should i use the same knots (2 half hitches) to tie the guylines to the tarp? What kind of line should I use? How do I tie and tension the guylines off with and without hardware (dutchware, nite ize, etc)
