Spring Breakers are drawn across the border to shop, to eat and to party. Quick trips to Mexico are perfectly safe as long as you stay on the well-trod tourist path and behave in a civil manner. (Hint: urinating on city streets is
not considered civilized behavior!)
Getting There
The best way to experience Matamoros is by bus; leaving the driving to someone else is a very good idea. There will be amny companies offering day trips for shopping and night trips for clubbing -- consult your copy of the most recent Coastal Current when you arrive on SPI.
The other alternative is to drive yourself - turn left on hwy 48 in Port Isabel and it will take you all the way to the bridge. While you can drive across the bridge, be warned that traffic moves very slowly and it is likely that your insurance policy will not cover your vehicle. The best plan is to leave your car on the US side. It will cost you about $1.50 to drive, or about .50 to walk each way.
