A storage method, comprising the acts of:

• movably mounting a plurality of storage units relative to a support surface;
• providing a vehicle for selectively placing items on and retrieving items from the storage units;
• selectively moving the storage units to form an aisle between a pair of adjacent storage units;
• and
• guiding movement of the vehicle along a predefined path formed along the support surface within the aisle.

A mobile storage system, comprising:

• a support surface;
• a plurality of mobile storage units;
• a storage unit guide arrangement for guiding movement of the mobile storage units relative to the support surface, wherein the mobile storage units are movable via the storage unit guide arrangement such that at least one storage unit in each pair of adjacent storage units is movable from a closed position throughout a range of partially open positions to a fully open position in which an aisle is formed between the pair of adjacent storage units;
• and
• an indicator associated with each adjacent pair of storage units for providing a perceptible indication that the storage units are in the fully open position.

A storage method, comprising the acts of:

• movably mounting a plurality of storage units relative to a support surface;
• selectively moving the storage units to form an aisle between a pair of adjacent storage units, by moving at least one of the storage units in each adjacent pair of storage units from a closed position throughout a range of partially open positions to a fully open position in which the aisle is formed;
• and
• providing a perceptible indication when the storage units are in the fully open position to form the aisle.
