On the very first post on this thread, Gary gives the comp details. Just under the 3 ABC choices there is a block of text in all capital letters, saying something like - ENTRIES FOR THE TRUCK PRIZE ARE VIA THE BLOG”. You need to click on that text line as it is a link (mine isn’t, you have to click on it in Garys post)
The blog will open in a new window. Scroll down all the way past the comp details, truck pics, legal stuff and peoples entries....it is a long way down. Right at the very bottom is a message box. Fill in your name and email and put your entry in the box there. Then hope you guessed right!
