Unfortunately, we do have to collect payment for people attending the Fourth HAAC, as we have facilities we have to rent and do not have sponsorship. The payment is the same as it has been for the last three years, which is $150 to attend for all three days, or $90 if you are presenting, or $60 if you attend for one day, or $0 if attend for one day and present.
Anyhow, to pay for HAAC you can:
1. Pay by buying a ticket on Eventbrite: Fourth Historical Analysis Annual Conference (HAAC) Tickets, Tue, Oct 21, 2025 at 9:00 AM | Eventbrite
2. Pay through Paypal at SRichTDI@aol.com.
3. Call TDI at (703) 289-0007 and pay over the phone by credit card (or by email at LawrenceTDI@aol.com).
4. Mail a check to TDI (8215 Wolftrap Rd, Tysons Corner, VA, 22182).
5. Pay by credit card, check or cash at the conference on the first day of the conference.
6. Pay by credit card, check or cash at Rangos on any Tuesday evening. I will be there after 7:00.
