We present a simple method for constraining the possible future positions of distant solar system objects observed twice over only a very short time span. The method involves taking two positions and then determining a large number of possible orbits compatible with the observed motion across the sky for an object with unknown (but constrainable) distance from Earth. A key advantage of this approach is that it assumes only that the object is bound and distant. Monte Carlo techniques are used to incorporate astrometric uncertainty and map out the allowed orbital parameter space. The method allows us to compute the object's position on the selected recovery date for each potential orbit, assisting the selection of fields for recovery observations. Examples are shown, and usage of the code is discussed.
