  We present near-infrared (JKs) time series data of the Large Magellanic Cloud
(LMC) cluster Reticulum. The observing strategy and data reduction
(DAOPHOTII/ALLFRAME) allowed us to reach a photometry accuracy of the order of
0.02 mag at limiting magnitudes typical of RR Lyrae stars. We are interested in
Reticulum, since it hosts a sizable sample of RR Lyrae (32), and therefore the
use of the K-band Period-Luminosity-Metallicity (PLZ_K) relation will allow us
to supply an accurate LMC distance evaluation. The main advantages in using
this method is that it is marginally affected by off-ZAHB evolutionary effects
and by reddening corrections. As a preliminary but robust result we find a true
distance in good agreement with the LMC Cepheid distance scale, i.e. DM = 18.47
+- 0.07 mag.
