Drawing Lines on Tennis Courts

I usually use tape measure and chalk to draw some lines on Tennis courts near me, since the nearest pickleball court is a 15 minute drive.

This usually works out well, as the chalk will stay as long as there's no precipitation. I also haven't heard any complaints from the tennis players

I'm curious if anyone else has to resort to "drawing" their own lines. And if so, what kind of solutions do you employ?
