I put myself between $5-10k but after reading about others who spent that much, I probably estimated high. I included incidentals at home too though. I've bought a lot of booze/beer that I wouldn't have otherwise bought but for a game on tv.
I go to one home game a year and spend about $150 on a ticket because I drive far and want one before I get there (also go early season). About another $150 on food, drinks, tolls, gas, parking, etc. That +200 for merch and home purchases such as rhise described above. Looks like about a $500/year habit. I guess I'm barely in that bracket at 1 game per year...
