2002, 2003, and 2004 Challenge. Finished in the top 10 each year, which was pretty cool.
2004 was a banner year- after blowing up the trans on our 3rd drag run, we swapped it for a spare, and I was fastest in the autocross the next day- this is a picture from that run.
The other highlight from 2004 was driving Angry's V8Vair. That was both an honor and a blast!
To be perfectly honest, right now, I'm kind of not too strong on the Alfa thing- virtually have dropped out of AROC, am not organizing events. If not for GRM, I may have dropped the whole car hobby thing. May not be back at the challenge any time soon, but if not for the ideas that I constantly get for it, I'm sure my enthusiasm would have totally gone away. So GRM/CM has done a lot for me holding onto what I have liked.
