I started watching Season 10 after watching Treasure Hunters (my flatmate at the time always laughed at the way Laird spoke, and his nose), being in the UK and not having satellite meant not really seeing much of it, but kept seeing people mention it on various chat rooms and torrent sites so started with season 10, got hooked proceeded to get access to seasons 1-9 and sat watching them all one after another (sometimes staying up all night to watch a season!), have stuck with it since although kinda lost it last season.
My fave season would have to be 3 mainly due to my home town being the end of episode 3 start of episode 4 (my friend actually did some static camera work on that season, but only told me he had worked for Jerry Bruckhiemer). I enjoyed season 8 probably because i'm not from the US and found it interesting to see the different places they were going.
