Sleeping bag & pillow (changes with season I use a cheap sleeping bag liner in the summer/b]
soap (liquid biodegradable available in camp sections of Walmart and Academy for dishes, shampoo and bathing)
hat (recommend a brim)
quick dry pants and shirts
medicines/spare glasses etc.
snacks like nuts, trail mix jerky etc
I like a sandwich like summer sausage on a bagel which packs well
For first night meals figure most will be grilling and either roasting vegetables in the coals or opening cans.
first aid kit
paddle and spare
This list is not an absolute, but simply a guide. Feel free to add and delete with each trip, experience and conditions.
Today I also carry a rubber hammer sold in Walmart and Academy specifically sold for tent pegs as is recommended further down.
Although my LED lantern is compact and very sparing on batteries I have increasingly taken to leaving it home using the moonlight, a clip on LED for my hat and a small LED flshlight worn on my belt.
Wash clothes and towels have been replaced with sham-wows which absorb fantastic amounts of water and are compact. That is both for personal washing and dishes. A sponge with scrub pad is cheap and handy in the kitchen.
Grilling is fun when you have a large group and everyone is making a production of it. In smaller groups and with burn bans I often use freeze dried food that only requires boilling water or canned goods that heat easily. The variety of canned goods and possibilties are increasing. My most recent additions is Margret Holmes Red Beans and Rice, Thow it is a pan and add a little sausage ( your choice which and you have a one pot meal. The coffee pot still goes for large groups, but often now I carry a 2 cup plastic French press avaiable in camping sections. Sometimes I even substitute hot teas.
I have added a water filter for multi-night trips so I so as not to carry as much cutting weight and space.
