While I appreciate BFGs; (experience and lockers can, often, overcome for a variety of sins).
The things that I would not go camping without are;
appropriate clothing,
a warm multilayered sleeping bag,
a tarp or poncho,
a medium fixed or locking blade knife,
and a working BIC lighter (preferably 3).
(some food is good too, as is some TP)!
... since becoming older and smarter (some say softer) I also appreciate a good tent, good comfy chairs, a cooler and cooking accessories (sometimes propane, sometimes campfire, based (depending on how I feel), good lighting and other more or less standard accessories.
Enjoy!
