Boquillas Canyon Trail
Interesting location as the Rio Grande is very shallow along this trail. There were maybe a dozen Mexicans selling trash and trinkets on the US side of the river and a couple groups offering horse back rides. Zero US .Gov presence, although all roads leading out of the park had Border Patrol stops. Our SUV wasn't searched but they did ask us to roll the tinted rear windows down.
Pro tip: ALWAYS take your sun glasses off when you are being questioned by US Customs or Border Patrol and NEVER be talking on your cell phone. Learned this while doing IT work at numerous Customs locations around the country.
