Re: Roll Casting question
When you practice you will need the resistance of line on the water to help load the rod.
An option if water isn't available is to tie up some grass leaders in which tags left at each knot to help the grass grab the line and load the rod. The problem with grass leaders is that you should have different length tags for different lengths of grass.
An easier and less complicated way to load the rod without water is to place the leader under a brick or something to hold the line tip while casting, step back to a little past the distance you want to practice at then slowly walk forward until, with the rod tip at 1-2:00 behind and above your head you have a loop of line behind you. Do a close equivilant to a standard overhand forward cast with all of the components of accelerating to a crisp stop and then watch your loop. You will just have the loop to go on as the landing will be in somewhat a pile around the block or brick.
