At the State Parks the sites come with picnic tables and nearby water pumps. The bathrooms are well-tended and the campsites are mostly shaded. All you really need is your tent and some sleeping bags, but other items would be most helpful too. You can buy firewood to use at your site, but you should bring along a camp stove.  Fold up chairs would be greatly appreciated. Bring all your food in a cooler and then keep it in the bear cabinet that is provided at every site.

Definitely bring your bathing suites, your bikes, your canoes and your rafts. You will be spending lots of time outside so make sure you bring your favorite toys and plenty of sunscreen. There are loads of eating establishments around the lake but go shopping before getting to Lake Tahoe to leave more time for fun and avoid paying a premium

The most common mechanism is the slip-joint. A spring placed between
decks, housed in the upper part of the handle, just press the heel of
the blade.
Pressure on the back of the blade enough to fold the knife, which is
never actually locked. The second mechanism is the lockback. The upper
part of the heel is made by a metal rod inserted between the plates at
the top and the blade is completely locked.

Just two other systems quite popular Linerlock and Framelock. On a
liner-lock, a tabletop is cut and served as spring. It folds into the
interior of plates when the knife is open, and put pressure on the
lower part of the heel.On the frame-lock, the principle is the same,
except that since the entire race is metal, so a portion of the
handle, which acts liner. The blocking is supposed to offer more
robust than on a liner-lock. Note to left-handers: liner and frame are
not ambidextrous systems. The choice of a system rather than another
depends on your taste and your use of the knife.
