Trying to remember every question or rule from year to year is never my strong suit. But I can get answers. Ron got it right, I checked and Waterford for their own open track days requires long pants and NO open toe shoes. Other than that, a shirt of some sort is necessary, but short sleeves are Ok.
I recommend a cotton long sleeve shirt though, if for no other reason than it makes it harder for a bee to get under your shirt as you are on the track!
As for the ones mentioning $$$ and a week long event. The event is officially 3+ days, but if you come early, it can be 4-5 or more. This is the annual VACATION for many people, and I will say it again, we tried doing weekend events for a few years, and it didn't work. Those coming for Saturday/Sunday then had a long haul home Sunday night or had to take friday and/or monday off to make a long trip.
We decided years ago this was a VACATION convention, and thus mid week solves a lot of problems. People have both weekends to travel and getting track events is a lot less expensive (and at least possible...most track weekend days are gone year to year and little chance to get in on a saturday or sunday) Restaurants easier to get into and other events less crowded.
Is it perfect for everyone? NO, but by consensus year to year, the during-the-week format is the best for the most people. If it doesn't fit your schedule, I am sorry.
As for $$$, these things don't happen on their own. We do our best to price it to break even. There have been several years when we lost money trying to be too low priced, and some years we made some money (always left in the account for the next year). You don't have to do every event, that is why it is priced ala-cart but we do require some cash to pay for things like paperwork, trips to find venues and restaurants and our costs to put on the event. the Banquet fee includes pay for help, cost of the facility and more. Our registration fee is low compared to other events that are similar, and compared to much larger events, we are low. We can't do all that larger events do, like live music (with a couple rare exceptions) or high paid speakers. But if you check out the events from past years, and talk to those that attend, I think we do a pretty good job for basically an event put on by our own family and a few treasured volunteers each year. It is rare when we have a support group that provides real advance help, but when we get that, we appreciate it.
But if you want to do the convention on the cheap you can still participate in a lot of events and mingle with a lot of good folks for not much money. Can't afford the host hotel? Then camp or get a room down the street. We work with one hotel that can meet all our needs, and it is easy to find alternatives if that is out of your price range.
Long drive? It is for a lot of people every year. but as I say every year, get a map, put a pin or mark every city or area we have been to and tell me we don't try to give everyone a chance for a short drive. Not in your area this year? chances are we have been in the past, and may be in the future. Have a suggestion for a location? We listen. But not every location works out.
We hope everyone comes, but obviously, that can't happen, even in the best of conditions. It looks like we will have a fairly typical turnout, a bit low maybe but very close, and registrations are still coming in.
I hope this helps some newcomers to the SHO world understand a little better about what and why we do things like we do.
