Depends on your plans. A few ideas:

Bug out: Take a day (weekend?) to practice some primitive survival skills - head into the woods and build a shelter, practice building fires (if safe and legal to do so in that area) practice making traps and snares. Practice using the tools in your kit. Test out all your gear. Can you really hoof it 10 miles with that 40lb backpack and a rifle? Does your vehicle have the right care/tools/supplies to help you bug out? properly inflated full size spare? extra food and water? warm clothes? jumper cables and tool kits? We practice and train in order to identify the gaps before we need to actually cross the bridge.

Bug in (it sounds like this is your plan... and I think this should be everyone's primary focus): Does your plan for heating the house really work as well as you thought it would? What about your plumbing/bathroom/sanitation situation? Are you prepared for broken windows? Do you have supplies to reinforce doors, cover windows, and secure your home? What about defense of home/street/neighborhood? How about non-SHTF home defense? Have you already taken good measures to make your house less of a target and more secure? Do you have duct tape, plastic, appropriate masks, tarps, etc? Are you prepared to stay in your house for several days completely sealed off from the outside?

Any situation: Good gun training is always applicable. Medical training and knowledge is never a waste. Having good organization and a written plan will go a long ways. Is your family prepared for bad situations too?

That covers a lot of things... many of which you've probably already done or considered - But hopefully if those suggestions don't apply to you, someone here can benefit from them.
