The best source for trike info - if you don't already know

If you want recumbent trike info, there is only one place to go - 'BentRider Online

Lots of info on all forms of recumbents, manufacturers, reviews, shops selling two and three wheeled 'bents, velomobiles. But little or no info on motorizing!
Mostly older guys and gals, but don't let that stop you from utilizing a good source of info.
