Great Chicken

Why is it that even the best recipes don't turn out when I have company?  I stumbled on a great marinade for chicken in an old Taste of Home magazine (olive oil, lime juice, garlic, spices) that made the most tender, best tasting chicken on the grill.  I only had 2 hours, vs 8, to marinate the chicken for dinner tonight, but it turned out dry and without the flavor it had the first time around.  I suppose I could blame the failure on my hubby's grilling skills..but I think the fault lies in my lack of preparation.  :-)  At least I made up for it with some VERY yummy brownies.  Quick tip from my mom-in-law--frost brownies with chocolate cake frosting.  YUM!
