The NEC one was cancelled when the other shows on at the same time pulled out. I went to the last Excel one and think the Bushcraft & Survival Skills magazine stand just about made it worth it what with the demos and all that. Part from a few exceptions there wasn't much bushcrafty stuff and quite why Crabbies and Yakult had a store there is a puzzle!
That said, Jason Ingamells said that Woodland Ways (who usually form part of the mag's stand anyway) have been asked so hopefully they'll be there. I think it's worth going at least once to see it but I wouldn't go unless the mag had a stand there again. If you are driving, it cost £15 to park last year.
