Here's a suggestion: How about offering a trip, maybe once a year, to England, or some other overseas location? Flights to London aren't much more expensive than flights to the West Coast.
I'd be curious to hear other people's thoughts on this.
Don't forget you have a local hookup here if you need contacts in the motherland for info, dart venues, anything dart related. I do websites for Phil Taylor, Robbie Green, Alan Green, and many other dart related sites. Feel free to contact me for anything you need. I'm local to you guys (Akron) and will help out in any way I can.
