I've caught them in the Trent Severn Waterway for the past 5 years or so.. Gloucestor, Little Lake, Severn River. I'd assume Simcoe has had them for that long as well.
Most of my good smallies this year (Yesterday evening for example) are coming off deep weed edges, top water bite which should be good hasn't been at all.. Ah well, the oldman and I like drop shoting for a change of pace.
