I came across these kinds of peculiar stacks of stones (most of them a set of 3 in each stock) during my visit to Avani Betta. As per the local legend, Seetha (wife of Lord Rama) stayed and gave birth to Lava and Kusha. And there is a general belief if the brides stack stones, the newborn baby will be a healthy.
On day one of 4 day road trip, we stopped near Tarikere on NH206 for breakfast. With two parallel tracks on either side of us, there was not stopping my niece jumping up and down whenever trains passed by.
