The variable width gate of claim 1, wherein the locking features include a detent to releasably secure the handle in the first position. 4. The variable width gate of claim 3, wherein the handle is disengaged from the detent to allow the handle to move from the first position to the second position. 5. The variable width gate of claim 1, wherein the first gate section and the second gate section collaborate to form a shield substantially isolating the at least one rib and the tracker from a user. 6. The variable width gate of claim 1, wherein: the second gate section includes the tracker; and the first gate section includes the at least one rib, wherein the at least one rib is operatively engageable with the tracker. 7. The variable width gate of claim 1, wherein: the second gate section includes the at least one rib; the first gate section includes the tracker, wherein the tracker is operatively engageable with the at least one rib. 8. The variable width gate of claim 1, wherein: the first gate section is slidably mounted to the second gate section; the first gate section includes a first stop limiting the second gate section from sliding beyond the first stop; the second gate section includes a second stop limiting the first gate section from sliding beyond the second stop; and an overall widthwise dimension of the gate is minimized when the first gate section approximates the second stop and the second gate section approximates the first stop. 9. A repositionable device to forestall movement through an opening, the device comprising: a variable width gate having an extender for expanding the variable width gate along a widthwise dimension thereof, the extender including a plurality of fingers and a mating boss, at least one of the fingers engagable by the mating boss; a repositionable handle movably mounted to the variable width gate, the handle operatively coupled to the extender to actuate the extender through movement of the handle relative to the gate, the handle being movable relative to the gate between a first position, a second position, and a plurality of third positions, the handle operatively engaging locking features of the variable width gate to lock the handle with respect to the variable width gate in one of the first position and the plurality of third positions; and an engagement between the at least one finger and the mating boss being operative to transform sliding motion between the at least one finger and the mating boss, in a first axial direction, into an expanding motion of the gate along a second axial direction to change the widthwise dimension of the variable width gate, wherein the first axial direction is perpendicular to the second axial direction; wherein the first position of the handle allows the widthwise dimension of the gate to be varied within a first predetermined range by maintaining the boss disengaged from the plurality of fingers, the second position of the handle allows the widthwise dimension of the gate to be varied within a second predetermined range by retaining the boss between an adjacent pair of the plurality of fingers, and each of the plurality of third positions of the handle inhibits variance in the widthwise dimension of the gate through engagement of the boss with the adjacent pair of the plurality of fingers, wherein the at least one finger comprises one of the adjacent pair of fingers and each of the plurality of third positions of the handle corresponds to a different point of engagement of the boss with the at least one finger such that moving the handle from a first of the third positions to a last of the third positions changes the widthwise dimension of the variable width gate, where the second predetermined range is less than the first predetermined range. 10.
