Fiona Rash, 2, plays on the bumblebee at Milligan Park on Wednesday with grandmother Lisa Davis at her side. The grandmother-granddaughter pair is not the only group taking advantage of mild temperatues and low humidity; others could be seen walking, using picnic tables for a casual lunch and playing frisby golf. Extended forecasts for the following week indicate high temperatures steady in the upper 70s and lower 80s, with a 60% chance of rain or thunderstorms Saturday.
