He'd hate it at our ground...............!
We have a semi-permanent hunter course set out and we let much of the grass grow, week by week. At the start of the season there are several targets that can be taken prone, not all but a substantial number. As winter gives way to spring, some of them become impossible as prone shots and become sitters (which SWEFTA allows) or kneelers.
By the end of May the grass is growing at a huge pace, and these shots become enforced kneelers otherwise you can't see them. Today, there are several that can only be taken standing.
So we get to learn and experience different shots and positions without having to do much, other than let mother nature have her way.
At the end of the summer it will all be cut back substantially, and that which isn't cut will fall over anyway.
