Thanks. Was that at Paga?
I'm asking because Ghana is frequently mentioned as a difficult country to enter--expensive visa needing to be purchased far in advance, etc. Any details are helpful; for example, many people don't want to transit so quickly, and a 48 hour visa won't work for them. And different border posts operate differently; I once entered on a little sand road from Togo where the border guards had never seen a visa, and I needed to explain it to them. They never even looked at the bike I was riding.
Any further details on any of what you listed? For example, I've only been given a transit visa entering Togo at the border. I've had a full visa issued by the embassy in Accra. Was yours a full visa, or just 2 or 7 days?
