Active Track - Grandkids tubing

[dveenhis]

I'd like to get some video of the kids tubing. I thought of using active track from in front of the tube. Has anyone tried this or used other techniques of taking tubing video?

I haven't done it, but if it's river tubing and you have lots of tubers, spark can sometimes latch on to another tuber passing close by.

Also spark flying backwards, have to watch for it running into anything.
