I'll second that, I went into Venezuela thinking I spend a few weeks and after more than 4+ months I'm still not done traveling around the country. Lots to see and do and the travel is 'free' with your own transport.
The people are more guarded than Colombians but once they open up to you they are great. The National Guard took good care of me when I asked to camp at their compounds and I met some wonderful people in Caracas off ADVrider that made my stays in Caracas wonderful, I spent way more than my fair share in the big town staying with friends.
The have island paradise of Los Roques and the tall peaks of the Northern Los Andes. You can even take you bike out to Margarita island cheaply for a little island touring and possible to go over to Trinidad if your came.
Nothing like the cheapest gas in the world, and don't forget Roraima and Angel Falls.

I crashed out big in Venezuela and can also recommend an excellent orthropedic trauma specialist
I left my bike down in Caracas and look forward to the day of my return
