There is use be a town called Topock, AZ. This was where the last stop from Arizona on route 66 to go into California and first stop to go into Arizona on route 66.
Topock was developed in 1883, as construction began on a wooden railroad bridge over the Colorado River. There is nothing left of this town.
Now what is here is a hotel and resort called Topock. You can ride your boat to this place and party at the bar, go swimming and there is a restaurant with great food. I read that is place is a popular hangout for spring break.
