Yea I plan on letting it go but didn't want to do it in my yard....I plan on taking it back to where it came from this weekend. I didn't know it was in there till after it was brought home. The Gray was the only one I noticed.....After doing some reading here and on-line I figured he would be best to go back and not mix them after reading some of your post and stuff here which I wasn't intending to mix and only wanted the Gray......Thanks for the advice much appreciated.
