Anybody else use codes/color tabs/abbreviations on their route cards? Or do you even use route cards? We use many and we use them often. TM = tank mix (Chaser ester) for hard-to-kill weeds. J/D = John Deere w/Spyker 220 electric spreader, R/O = ride-on sprayer/spreader, Z2 = Z-Two sprayer/spreader, pre x 2 = two app's of pre-emergent, commercial accounts (weekends only), etc. We use different color tabs on all our route cards to distinguish between these accounts. It's just like a doctors's office........they too have files on everyone, and each file has color codes for specific needs. Just curious if anyone else besides us does this too?? rscvp, thanks, americanlawn.
