I've only been to two firesides - one during the season where much of the team was present (that's the typical format) and this last one in Dallas where only Bronco and the two players (Dustin and Manaaki) spoke. There was one other incoming freshmen in the congregation (Michael Yeck), but neither Tom Holmoe nor Pres. Samuelson were present. I suspect those two are already in Chicago for some other function and they're combining for that fireside. I noticed it's at a hotel rather than at a chapel.
Coincidentally, members of the football operations staff were in attendance - they had been in town negotiating arrangements (hotels, etc.) for the TCU game. Apparently the schedule was finalized so late that they couldn't make reservations until now. Another Thursday night game at TCU.
