I went from just liking coasters to actually taking an interest in the designs and suchlike whilst planning my trip to the US in August '07. However, I still wasn't a true enthusiast at that point, and had no idea of what a "credit" was. Therefore, the only park we went to was SFMM, and even then, didn't get all the "credz". When in Vegas, we only rode Speed. However, we had an amazing time and enjoyed everything we did ride. The difference is, that it was just a holiday, where we happened to ride some coasters while there. If I went again now, the entire trip would be planned around park visits and coasters.
That change happened after I joined CF in Nov '07. I'd been spending a fair bit of time learning about different types of coasters and maufacturers etc. For me, it made trips to parks more interesting, as it meant I could make more informed comparisons between different coasters etc. I decided that if I wanted to learn more, it'd be a good idea to join a forum. I googled, and after discounting several others for being non-UK based, park specific, pay to join, or just generally crap... I found CF
I quickly discovered what a "credit" was and worked out that, at that point, I already had 36 (plus probably a few more from when I was tiny... but if I can't vividly remember it, then it doesn't get counted). I very quickly went to places where I'd never riden rides before (Southend, Brighton Pier), and a few that I'd been to as a kid, but had new "credz" to get (Lego, Chessie, Drayton). I also went back to Alton and made sure to get the Beastie "cred". I was now up to 49, but wanted to up the ante...
So went on my first live! The Yorkshire Tripper in May '08. Since then I haven't looked back. I've been on loads of trips with CF (both Lives and private trips) to a lot of parks that I never would've been to otherwise. It's also taken me to places that I never would've seen otherwise (although, that'as not always a good thing - 2 trips to Belgium in one year?!). It's a fab hobby and I'm glad I got sucked in. Not to mention, of course, all the fantastic people i've met and amazing friends that I've made.
So I'm currently on 162 "creds". It's unfortunate that I've had to take a break from parks this summer, and I really miss it. I can't wait to get back on a coaster, and GF can't come soon enough. As for new "creds", it's mainly lack of money that's stopping me making any plans at the moment... but that'll just make it all the more exciting when the opportunity does come about!
Woah, that was long. Sorry.
