While more than 100,000 visitors are expected to visit Austin for the big race this weekend, the Capital City isn't the only spot visitors will be stopping.
Lee Levan and Roger Cook are driving their RV from Florida to Bastrop for the U.S. Grand Prix this, but stopped in San Antonio first.
"We had to see the Alamo,” said. “You come to Texas you have to see the Alamo."
For Australian Terry Cummings a stop at the Alamo was a dream come true.
"Ever since I was a little kid I've been reading stories about Davy Crockett,” Cummings said. “Basically, I just wanted to come here and the F1's on so everything sort of fits into place."
Jim and Susan Cole are in town from Minnesota. The Alamo had a larger impact on them.
"It played a bigger part in our history than what I realized," Jim said.
As a long time motor sports fan, F1's return to the U.S. was too much to miss.
"This was our first chance to attend a Formula 1 race in this country and the track looked really great on TV, we thought hey let's go for it," Jim said.
Rod and Carrie Eva live just outside London. They've spent the last week touring Texas and say almost everywhere they went they found race fans.
"When we went to NASA, we did a tour for 12 people, the level nine tour, eight people on it were going to the race," Carrie said.
After the Grand Prix, their Texas tour will continue.
"Have to go to South Fork just because. South Fork, Dallas, TV program," Carrie said. "We want to see if it really exists."
It does and with a stop there, their Texas trip will be complete.
Many of the race fans said, while the race is the main reason for their trip, they're making the most of their visit to Texas.
Some said they were also planning to visit other states before they left the U.S.
