If you are boarding this train ONLY to receive the most free seed possible, then PLEASE exit now. THP is FULL of folks that will send you free seed. But to dead-end the train, horde seed, or disappear with the package(s) altogether isn't useful to anyone. The success of the train depends on ALL its riders... and it works well!
I believe thats why people have to have at least 50 posts or more if I recall from previous activities.
