Letting un-boiled wort sit overnight

[berley]

Does anyone here do this? I know there's several people who do overnight mashes to save time. What about doing the mash, mashing out to stop enzyme activity, draining and sparging into the kettle, and the completing the boil the next day?

I've read varying opinions. Some seem to be worried about infections that won't necessarily be completely killed by the boil. Would I just be better off heating the wort to ~200 F, then covering it and letting it sit until the next day? If I mash out to close to 170 F, there'd only be a 30 F difference there...

Thoughts?

I do this sometimes. i ususally bring the wort up to 185 and cover it for the night.

I've done my mash on a weeknight, drained into the kettle and brought it up to a boil for a few minutes and then covered and left it until the next day after work with no problems.
