Thanks, I'll have to give that a try. My rum additive has mostly been Tonic over the years, quite refreshing....
Speaking of Fresca, in a small town Package store recently, the proprietor told me that Coca Cola was phasing out Fresca..... my limited investigation says that is BS, but one never knows. Up here in the NW, at virtually all the stores, Fresca is sold out quite often, while the rest of the Coke products seem to proliferate.
