Not heard of them, are they Mission or Chilliwack based ?
i hope they are ok or your mates have used them before as there are some on the river that want to make good money by using their private boats and shiny websites to lure clients, when they don't have much of a clue about the finer points of sturgeon fishing, because while "chuck a bait in and wait till the rods folds over" will undoubtedly catch a few fish,there is far more to it than that, so they won't be consistent and if the going get hard, will be clueless.
that said however the place is awesome and I hope they have a blinding trip !
