Best way to arrive to show is by Max.  The Oregon convention ctr has limited bike parking.  Also the parking garages fill up quickly (by 9 am yesterday).   Please walk, take bus, or take Max to the show.  Biking is great, but just be aware of limited bike parking. 
No bikes are allowed to be brought inside except by registered exhibitors with credentials.  All bike parking is self lock too. Bring a lock!
