Anyone had any success yet with smallmouths on the Little Miami River in southwestern Ohio? Looking to hit it within the next week or so, in general the fishing here has been slow due to weather fluctuations.

You may want to look in regional reports or ask the question there rather than in the smallmouth section.  I have never fished the little, but I have some good success on the Great Miami.  I will say this, too; bassresource is by far the best forum for techniques/guidance/equipment reviews/ etc., but for fishing reports I would say go to www.ohiogamefishing.com and look under the regional fishing reports on there.  They are typically not willing to share much information, but you are more likely to find some type of report on LMR there than you are on here.  PM me anytime!
