In way too long - I haven't even seen Furthur yet - last show was NYE '09!!
Having them north of the border is always a treat - last time I can remember was a Halloween show Ratdog played at a small club in Toronto (http://ratdog.org/2005-10-31). Not many heads up here (which sucks) but it guarantees great seating and an intimate setting.
It would be great to meet up with any kind folk making the trip.
