Parking
Lewis & Clark Park and parking viewed from the south
$1 but ample
One large concrete parking lot, but you only have to pay a dollar. Some may try parking on Line Drive, but this is (probably) ticketed so the city gets all its money from the parking concessions (and it's a bit of a hike anyway)..
Tailgating
Early tailgaters at the ballpark (1999)
Yes, some
There were no signs of tailgating in '93 & '94.
But now there are definitely a tailgating crowd at X's games now. After a "big game" (like fireworks nights) there's a crowd before and after the game.
