Flat Tire Help

[bennynomad]

I went for a ride Saturday in the N. Georgia Mountains and somewhere along the way picked up a 2" screw in my back tire. I didn't notice it until Sunday morning getting the bike out and I couldn't move it because the tire was flat. I pulled the screw and tried to plug it, but I cant't get the plug in the tire. At that point I just wanted to get it inflated so I could get it to a dealer for a new tire, so I used Inflate a flat. I know a no-no, but at the time I just wanted to get it up! . Well, that didn't work either. I can't get the plug through the hole, I have never plugged a tire either. Anyone have ideas? I want to get it to hold long enough to get the bike to a dealer near me on Friday and have it replaced. I have alot of riding to do this weekend, suppose to be nice. As you can tell I am not a top notch mechanic, so no I do not want to take the back tire off. Help!
