Has anyone snowshoed to Kachess campground recently? I wanted to do an overnight on Friday. It's looking to be freezing cold so I wanted go to a non-backcountry location with a short hike in. I know the campground is closed but I figured I could pitch a tent in the snow. Thanks!

You'll need a sno-aprk permit to park at the Kachess sno-park

You'll also need to dodge the snowmobiles while hiking the road to the campground road cut off. 
I suspect that snowmobiles also razz around the campground loops and on the lake bed exposed by the winter draw down -- at least during the day.   Should be a bit quieter at night,  but I would choose a tent site surrounded by trees so your snow covered tent in the morning doesn't look like a good "jump" to razzers.   I would also think about some sort of reflectors to hang on the tent or off of treking poles placed around the tent.
