Move along, nothing to read

Travel, accommodation, food, registration costs. The exhibit hall is free at OSCON, but the other admissions used to start around $1200.

My ballpark budgeting figures below. Food based on $50/day. Couch-surfing or sharing rooms for accommodation.

MySQL UC: $400 travel, $200 accommodation, $300 food, Sponsored reg. = $900.
LinuxCon: $0 travel, $0 accommodation, $200 food, $400 reg = $600.

Linux Symposium: $600 travel, $500 accommodation, $300 food, $100 reg = $1500

FOSDEM: $1200 travel, $300 accommodation, $300 food, Completely free reg = $1800
SCALE 9x: $400 travel, $200 accommodation, $200 food, Sponsored reg. = $800
OSCON: $200 travel, $300 accommodation, $300 food, Free exhibits reg only ($1200+ for more) = $800.
