Game carts

Was wondering if anybody out there has ever seen or used a game cart that can be attached to mountain bikes. I've strapped deer to the bike itself, which has worked okay but would like to find an easier way to get them out. I know they're out there, but can't seem to find them anywhere. Any ideas?

I have one, but it is a bit noisy to tow when empty, not making it very stealthy. It is a kid cart, built for two. It will handle a deer, or half an elk. It also has a front wheel that will attach, making it a three wheel cart. All wheels are pneumatic, and we got ours at Toys R Us.

I will usually drop it off in a central area I am hunting, then come back for it if we need to haul something out.

I'll try to take a photo or two tomorrow.

I've also seen trailer systems for packing camping gear behind Touring Bikes. I don't knopw where to find one other than at one of the Bike Shops, arround the sound.
