Now, some answers:
If you're looking for anything else to add to the itinerary, I'd suggest the one-lane truss on SR 225 over the Wabash. Not too much of a detour from the new IN 25.
It's a possibility, especially since we'll pass very close to it on old SR 25. However, there's a lot of ground to cover (the Lafayette/West Lafayette half could almost be a full meet on its own) and sunset will be around 5:30, so I will have to leave out some material in the interest of time.
Is there anything on Sunday the 11th or is this just a Saturday only meet?
This is a Saturday only meet. I know there are folks staying in the Lafayette area on Saturday night, so we could arrange a post-meet dinner if there's interest. I'm not sure of my Saturday night plans because I have a family obligation in Michigan on Sunday but don't know what time it is yet.
I've never been to a meet before but I would be interested in this one. I have a niece who's at Purdue and my wife and kids have been talking about taking a day to go visit her and the campus. Could I get dropped off somewhere, ride with someone else, and get picked back up somewhere?
Yes. To elaborate on Brandon's response, the roadmeet will start with a group lunch at a local restaurant. Then we all tend to carpool for the duration of the tour. We'll drive around the Lafayette area and then head out to Logansport and back, making periodic stops at the bigger points of interest. The meet ends where it began since that's where the non-drivers are parked.
I just found out Lafayette has a Dog n Suds. That may be dinner Friday night 
There are two! I ate at the West Lafayette location earlier this year and it was excellent.
