I know many fishermen go to Panama for fishing from January.
On my last trip to Pamana during Christmas Holidays, I experience two new things.
One is Tourist Card
When I went to the gate to aboard Continental, they announced to purchase Panam Tourist Card for $5 before boarding. They insist it would be higher when they purchased after aboarding and didn't say who are required.
I found out later that only passengers with American passport are required to purchase the Tourist Card. You can purchase the Tourist card exactly same amount of $5 before immigration check at Panama.
The other thing is FISHING LINE.
I traveled to many different countries and the only country which prohibit fishing lines on carry-on bags at security point is Costa Rica. You have to get rid of all lines from reels at security point.
I traveled to Panama four times last season and I never had problem to bring reels filled with lines at security check in Panama until last trip.
I checked in all reels and I put a few rolls of fishing lines in my carry-on bag. They try to forfeit those lines at security point when I flied back to NJ from Panama. I protested it, but even the supervisor told me fishing lines are not permitted.
You can not fight against stupidity. So I told the security lady that I would go back to check-in counter and check in the bag with the lines, but the lady said NO. I did not back off this time and protested hard. The supervisor reluctantly let me go back to the check-in counter and I checked in the luggage ( I had one more room for check-in. ).
