..."MAKE" YOUR OWN.
Check this out...
This "invention" allows cyclists to "mark" their paths with a faint contrail of CHALK.
By using this device, bicyclists will have a clearer path on which to ride safely and out of the way of vehicular traffic. At the same time, as more bicyclists using the Contrail go over a line created by a cyclist before them, the line gets brighter allowing drivers to clearly see a marked bike path where there might be none. It's sort of similar to what happens when a dirt path appears in a grassy field after lots of people have taken the same shortcut over a period of time.
