Funny how well-worded that chorus is for that song... I have it on vinyl somewhere and internalized that lesson many many moons ago.

Always have a backup plan!
Know how you will bail out before you hang your first light. Know the numbers for van rental shops (I don't like box trucks because of the risk of running into a weigh station or DOT inspection). Have a storage unit in another county. Dispose of waste regularly, so there isn't a ton of it- literally- sitting around that you will have to deal with when you bail. Have a safe place to store your product, like a trusted friend who will house a suitcase full of mason jars for a few days if you get that funny feeling.

And rule #1: Trust your gut. If you gut says "BAIL!", do it. 2kw worth of weed is still less than the attorney fees on a grow arrest.
