Long time Season Ticket holder here. Have been to a few bowl games, but they are usually quite costly. Ticket prices are high, and air fares are ridiculous at this time of year. Would much rather travel to regular season away games (went to Nebraska this year). However, I did put in for tickets to the OSU Clemson game as my brother lives in the Phoenix area and hit me up for the tix.
As I understand, OSU ticket requests for the bowl games generally favor OSU applicants who are closer to the location - hence, living in Washington State I'm a little higher up on the hierarchy for the tickets. That is another reason you see so many west coasters at the western bowl games. And, of course, there are quite a few fans out here who will buy their tix on the secondary market as they can make travel plans fairly easy if they find a good price on tix.
As for me this year, we have a brand new 70" Vizio that was much cheaper than buying tix and traveling to a bowl game. Will have the family over for a fun time.
We have also been to Glendale to see the Buckeyes play before. We really do not like that stadium. It is perhaps the worst modern stadium for a football game. Would never go back to see another game there.
