i actually trunked it wedneday and thursday, but needed rubber for tuesday before the warm up. i might try to trunk tomorrow, because it might be the last day i can until next june. my rule is if the water is at least 65, and the air temperature is over 65, and not windy then i can just go in trunks. usually below 65 water temperature, and below 65 air temperature i start adding rubber. i'd say around 60 for me is when i start putting on the boots.
