How's it going Larry. Hope you remember who this is. Met you in Louisville at the sports show. Anyway, you gonna do Reelfoot again, good. You do that every year don't you?
Don't know too much about Grenada, but if you're going to drive 9-10 hours, you might as well add a couple more and go to Hamilton or Greeson in Central Arkansas. Links are on my website (click below) and if you decide to go, I'll see what I can do to point you in the right direction on the lake. There are bunches of resorts and places to stay in Hot Springs.
If you're just looking for a different place to fish and camp, you can tryout Lakes Poinsett and Charles here in northeast arkansas close to my home. Those links are on the website too. Both are only about 1.5 hours west from Reelfoot. There are usually a dozen or more seniors who camp at Charles each spring for 4-6 weeks straight. Nice folks. Descent crappie too.
